Aluminium Chromium Master Alloy Al-Cr alloy

Aluminum-Chromium (Al-Cr) Master Alloy is an alloying additive used in the production of aluminum alloys, where chromium (Cr) is introduced to modify microstructure and improve specific mechanical and physical properties. It is typically used in small percentages due to chromium’s strong grain refinement and strengthening effects. 

Typical Composition

• Al-Cr 2%, Al-Cr 5%, Al-Cr 10%

• The final chromium content in the end-use alloy is typically 0.05–0.3 wt% depending on application.

Applications

• Aerospace Alloys

  • Used in alloys like 2xxx, 5xxx, and 7xxx series for high strength and corrosion resistance.

• Automotive

  • Applied in suspension, chassis, and body components for improved durability.

• Aluminum Rolling & Extrusion

  • Helps stabilize grain structure during processing.

• Heat-Resistant Applications

  • Chromium enhances oxidation resistance in aluminum parts exposed to elevated temperatures.

Forms Available

• Ingot

• Waffle plate

• Shot or granules

• Powder
