Amtec 435 FC aluminum torch rod is a unique product that contains a highly active flux core, sealed inside the alloy, which allows for easy application and very economical use. The melting range of this flux is controlled to ensure that the alloy yields dense, non-porous deposits with minimum flux residue. Its fluidity at higher temperatures enables it to have free flowing characteristics when used on lap joints or around tubing. Likewise, its high viscosity at lower temperatures allows it to fill gaps or build up sections. Color match is good on most aluminum.
