4004 Aluminum alloy,Aluminum 4004 alloy,E FORU

### **Product Introduction: Aluminum 4004 Alloy** **Overview** Aluminum 4004 Alloy is a heat-treatable aluminum-silicon alloy specifically designed for brazing applications. It contains silicon as the primary alloying element along with magnesium, which provides precipitation hardening capability after brazing operations. The alloy is particularly valued for its excellent brazeability, corrosion resistance, and the ability to develop good mechanical properties after heat treatment. 4004 is commonly used as cladding material or brazing sheet in heat exchanger manufacturing. --- ### **1.
