Can 2024 Aluminum Be Welded To Aluminum. It can range from “very good” to “unweldable by common arc. Aluminum alloys of 2024 and 7075 can become susceptible to stress corrosion cracking after welding.

Essentially pure aluminum (99 percent pure) and used to carry electrical current or for corrosion resistance in specific environments, these alloys are all readily weldable. Our experts explain why welding 2024 vs 7075 alloys is not a good idea.
