Product Information

dented metal, prior to powder-coating — when Lab-metal cannot be used due to the extreme temperatures. If a spool of aluminum wire isn’t going to be used cover the spool with the plastic bag the wire shipped in or with another protective cover. TIG cut-lengths are best stored in their original box to protect against dirt and debris. Material hardness and strength depend on alloy composition and heat treatment (solution heat treatment and quenching followed by either natural or artificial ageing produces a fine dispersion of the alloying constituents). Principal alloying elements are defined in the 2xxx, 6xxx and 7xxx series. Fusion welding redistributes the hardening constituents in the HAZ which locally reduces material strength. Processes

Hi-Temp Lab-metal must be stirred thoroughly before use. No additive is needed; the repair compound hardens upon exposure to air. Hi-Temp Lab-metal is a viscous but easily spreadable paste. Upon opening the can, if the Hi-Temp Lab-metal appears stiff, stir in a capful or two of Lab-solvent to restore the product to its appropriate consistency. For any application, the surface must be clean and dry; free of paint, oil, dirt, and any extraneous materials. Roughening the surface provides superior adhesion. Hi-Temp Lab-metal’s shelf life is one year in factory-sealed cans. Store in a cool place. See MSDS for safe handling. There are many aluminum filler metals available in the marketplace, including those for applications found in aerospace or architectural structures to filler metals for heat exchangers, trailer fabrication and more. The filler metals range from pure aluminum to varieties with added copper, silicon or magnesium. Our Aluminium Trihydroxide Filler Powder is compatible with all popular casting resins, including polyurethane, epoxy and polyester. Yes, marine epoxy is designed to adhere to aluminum. It forms a strong bond that can withstand extreme weather conditions and harsh environments. However, it’s important to make sure the surface of the aluminum is properly prepared for the epoxy application. Before applying, you should clean the aluminum with a solvent or degreaser, then lightly sand or chemically etch it. This will ensure the best possible adhesion between the epoxy and aluminum. Additionally, make sure you select an appropriate type of marine epoxy for your project – some are better suited for specific applications than others. With proper preparation and selection of epoxy, you can trust your repair job will last for years to come. What can you put on aluminum to keep it from corroding? As a rule, this factor does not influence the quality of repairs if the issue needs to be fixed. It does not matter how much time it will take to do it if you need a satisfactory result.Aluminium trihydroxide is an inert, odourless filler powder than can be used to reduce shrinkage and add weight to cast polymer products. It can also improve the fire resistant properties of the casting and reduce exothermic reaction. Among the variety of aluminum filler metals, 4043 and 5356 alloys are the most common and the least expensive. Together, those filler metals are used for welding about 80 percent of the time and are available in wires for MIG welding or cut-lengths (often called filler rods or straight lengths) for TIG welding. Knowing how to choose between the two alloys, as well as the characteristics each provide is important to producing good weld quality. A spool gun or push-pull gun for the MIG welding process. These guns provide consistent feeding of the aluminum filler metals, minimize wire feeding issues and allow for welding further distances from the wire feeder (often as far as 30 feet away). Applications where distortion is of particular concern, as it minimizes this defect.
A 5356 aluminum filler metal would be most appropriate for: Hi-Temp Lab-metal is recommended where original Lab-metal may not withstand the extreme heat. Originally developed due to requests from the foundry industry, industries such as metalworking, powder coating, welding, fabricating, heating, construction, auto repair, die casting, mold refinishing, and sheet metal production and finishing have found uses for Hi-Temp Lab-metal. It successfully repairs:

Remember that not all epoxies are good for painting. However, if you have applied one that allows for it, use a self-etching primer. This formula includes the chemicals that help micro-etch the surface you are going to paint. Is Gorilla epoxy good for aluminum? Dipping, spraying or wiping with organic solvents can be used to remove grease, oil, dirt and loose particles. Aluminium and its alloys can be readily welded providing appropriate precautions are taken. The most likely imperfections in fusion welds are: With an open time of ca. 15-20 mins and a curing time of ca. 2 hrs at 22°C, 3M™ FC Epoxy Metal Filler enables fast processes in the body shop. It is also possible to further speed up the curing by using IR drying. You need to know the conditions in which your repaired surface is supposed to function. Consider the highest and lowest temperatures possible. Sometimes, that can become a critical indicator. Overall Look and Ability to Be PaintedApplications that will be subject to long-term elevated temperature exposure (above 150 degrees Fahrenheit). Applications where aesthetics are particularly important, since these filler metals provide bright, clean welds. In any welding application, the goal is to complete the job with high quality and efficient results. Speed and weld integrity are just as important when welding aluminum as any other material. Knowing the basic filler metal characteristics and selection criteria for applications employing this material is a good first step in getting the best welding performance. Additional practice with welding this material — especially for welding operators new to the material — is also a good idea. Consider welding scrap materials as a starting point to get a firsthand experience of the different operating characteristics of aluminum filler metals, including the 4043 and 5356 alloys discussed here. And when additional information about the aluminum welding process is necessary, look for resources with a local welding distributor or filler metal manufacturer to help. They often have technical support specialists to offer advice. Use the 80-grit aluminum oxide paper to abrade the surface before applying the sealant. Mind that aluminum is nonporous so sandpaper may not always be useful. Ensure that the surface is solid, so you need to remove all the blistering, old coating, flaking, and chalking before the application. Do I need to prime the aluminum before painting?

That depends on what the aluminum is being used for. The most common type of coating for aluminum is anodizing, which provides a durable finish and helps protect it from corrosion. Another option is powder coating, which can be customized with various colors and textures and also provides protection. There are other options such as chrome plating or galvanizing that are best suited to certain applications. Ultimately, your choice will depend on the intended use of the aluminum and any specific requirements you may have. Thin with Lab Solvent to ease spreadability. Typically dries in 24 hours, heat cure at 425 degF for 1 hour before exposing to high temperatures. Great for filling surfaces before powder coating where 2 or more coats are required. Material strength depends on the effect of work hardening and solid solution hardening of alloy elements such as magnesium, and manganese; the alloying elements are mainly found in the 1xxx, 3xxx and 5xxx series of alloys. When welded, these alloys may lose the effects of work hardening which results in softening of the HAZ adjacent to the weld. Heat-treatable alloys To apply Hi-Temp Lab-metal with a paint brush, it must be thinned to paint consistency with Lab-solvent, then applied with light brush strokes; not worked over as with paint. Dipping the brush into Lab-solvent periodically will keep the bristles free and prevent clogging.

Filler alloys

Porosity is often regarded as an inherent feature of MIG welds; typical appearance of finely distributed porosity in a TIG weld is shown in the photograph. The main cause of porosity is absorption of hydrogen in the weld pool which forms discrete pores in the solidifying weld metal. The most common sources of hydrogen are hydrocarbons and moisture from contaminants on the parent material and filler wire surfaces, and water vapour from the shielding gas atmosphere. Even trace levels of hydrogen may exceed the threshold concentration required to nucleate bubbles in the weld pool, aluminium being one of the metals most susceptible to porosity. When welding 6XXX series aluminum or 5XXX series aluminum containing less than 3 percent magnesium, it is possible to use either a 4043 or a 5356 filler metal to complete the job. The same holds true for higher shear strength applications; however, it typically takes three fillet passes with a 4043 product to equal the shear strength of one pass using a 5356 filler metal.
Proper storage and handling
Proper storage and handling of aluminum filler metals is essential to ensuring the highest quality welds. It is important to keep the filler metals in a clean, dry area that is of a similar ambient temperature as the weld cell. Moving them from a cold area to a warmer area could cause condensation to form on the surface of filler metals and lead to poor weld quality. Providing the base metal is compatible, a 4043 aluminum filler metal will be best for the following: In addition to proper selection, storage and handling with 4043 and 5356 filler metals — or any aluminum filler metals for that matter — it is important to have the right welding equipment for the job. This equipment includes: U-groove drive rolls. These drive rolls prevent the wire from being pinched or compressed, and help ensure proper wire feeding.
