Al-Si EXCELLENT HIGH ELASTICITY AND WEAR RESISTANCE HYPER-EUTECTIC AL-SI ALLOY

摘要

The present invention relates to a super-process Al-Si alloy excellent in elasticity and abrasion resistance, and more particularly to a super-alloy Al-Si alloy excellent in elasticity and abrasion resistance, comprising about 13 to 21% by weight of silicon (Si) (Ti), about 4 to 5% by weight of titanium (Ti), about 0.7 to 1% by weight of boron (B) and the balance of Al and unavoidable impurities. Si-based alloys through an additional strengthening phase such as an Al3Ni generation phase produced by nickel (Ni) or the like which can be reinforced and improved by improving the abrasion resistance, And an over-process Al-Si alloy excellent in abrasion resistance.
