ZL109 (ZAlSi12CuMgNi) Piston Casting Aluminum Alloy: Eutectic Silicon Aluminum-Nickel-Copper-Magnesium system for high temperature strength and low expansion.
As a typical representative of aluminum-silicon-copper-magnesium-nickel eutectic alloys for pistons in the Chinese national standard (GB/T 1173), ZL109 (ZAlSi12CuMgNi) is known for its excellent high-temperature strength, good wear resistance, low coefficient of thermal expansion and excellent volume stability. The alloy ensures low expansion and wear resistance through high silicon (Si) content, supplemented by copper (Cu), magnesium (Mg), nickel (Ni) multi-composite reinforcement, and after T1 (natural aging) or T5 (artificial aging) heat treatment, it can obtain excellent high-temperature mechanical properties and dimensional stability, and it is a special material for manufacturing pistons of internal combustion engines and other heat-resistant and wear-resistant parts subjected to alternating thermal loads and mechanical loads, which is known as the “piston alloy family”. "It is a specialized material for manufacturing internal combustion engine pistons and other heat-resistant and wear-resistant parts subjected to alternating thermal and mechanical loads. The corresponding national grade of ZL109 is ZAlSi12CuMgNi. ZL109 Aluminum...
