✜ Development History

Motive for Development

ㆍ For reducing weight for car, Applying special B390 Aluminium alloy (high silicon material) to diecasting process
ㆍThe other company failed to develop this product with B390 Aluminium alloy because of low productivity

Development History

ㆍReceiving a request for development in February 2006
ㆍMass production was begun in 2007

Process method for this product

ㆍMetal Pressure : 850kg/㎠
ㆍSilicon Refining : CuP Processing
