Hypereutectic aluminum-silicon-based alloy having superior elasticity and wear resistance

摘要

Disclosed is an aluminum alloy having superior elasticity and wear resistance. The aluminum alloy has superior elasticity and wear resistance and improved wear properties by including additional reinforcing phase formation such as Al₃Ni phase formation. In particular, the reinforcing phase may be generated by adding nickel (Ni) that may reinforce and enhance properties which may be decreased due to generation of a ternary phase such as TiAlSi. The aluminum alloy comprises an amount of about 13 to 21% by weight of the silicon (Si), an amount of about 1 to 5% by weight of the nickel (Ni), an amount of about 4 to 5% by weight of the titanium (Ti), an amount of about 0.7 to 1% by weight of boron (B), and a remainder of Al based on a total weight of the aluminum alloy.
