摘要

Aluminium alloys resistant to abrasu00e7o, method for produu00c7u00e7o a motorcycle cylinder block of aluminium, method for produu00c7u00e7o a molten Al Si alloy and an engine block of aluminium.The present invention relates to a composition of aluminium alloy silicon affects the conditions of production and performance for engine blocks of cylinders without lining using processes such as smelting of low cost molds silica sand.The alloy of the invention corr preende, in% by weight: 13% - 14%, 2.3% - 2.7% Cu, 0.1% - 4 ~ Fe; 0.15 - 0.45% Mn, 0.1% to 0.30% Mg, 0.1% - 0.6% Zn, 05; ~ - 0.11% Ti; 0.4% - 0.8% Ni; 0.01% - 0,09% RH; and the rest being aluminum plus any remaining elements.This alloy has the characteristics of machining very good, giving a surface finish of signifiicativamente improved in the holes of cylinders.The production cost of the engine blocks is reduced by about 40% compared with the alloys CC merciais in current use of the previous technique requiring liners of any primary iron itself this is substantially uniformly disper & and copper do not secrete during solidification And the cooling.
