705 Aluminum

705 aluminum is an aluminum casting alloy commonly used in industrial and automotive applications where good strength and wear resistance are required. It is known for its solid mechanical properties, pressure tightness, and ability to perform well in structural and load-bearing cast components.

705 is often selected for castings that require strength, durability, and reliable performance under load. Common applications include:

• Automotive Components: Transmission housings, differential cases, brackets, and structural components
• Industrial Equipment: Pump housings, valve bodies, gear cases, and machinery components
• Hydraulic Components: Parts requiring pressure tightness and dimensional stability
• Heavy-Duty Castings: Structural components that need higher strength and durability
• General Industrial Castings: Applications requiring good machinability and mechanical strength

Primarily aluminum with approximately:

• 6–7% silicon
• 0.5–1.0% copper
• 0.4–0.6% magnesium
• Small amounts of iron, manganese, and zinc

(Exact ranges can vary slightly depending on specification and foundry.)
