Description:
Aerospace Material Specification 4245 is composed of aluminum alloy C355 welding wire in gas-tungsten-arc (GTAW) and gas-metal-arc (GMAW) welding. Contains a low amount of iron to create higher tensile properties. Designed for joining and repairing. This alloy is an Aluminum-Copper-Silicon alloy used for casting alloys made of similar composition.

Available in multiple diameters and sizes in straight length wire and in spools.
