Magnesium Automation of die-casting : It is possible for producing Mg by hot chamber, because Mg is difficult to react with steel. Life of metal form : 주조용금형은 Mg용탕과 반응하기 어렵기 때문에 수명이 Al의 수배이다. High productivity : Mg become solidified so fast and is possible for getting lots of casting per hour due to taking low heat capacity compared to Al. (Generally, bring more productivity about 40 to 50 % than Al). Safety of size : Mg is superiority over safety of size and has constant contraction rate for die-casting. It is possible for pre-estimate of contraction rate. (can minimize deformation, remaining stress and correction in taking out a product from metal form) Processing ability for M/C : Merits of Mg as to processing for M/C. Power required for cutting is low due to low elastic coefficient and resisting force. ( in the case of 1.0 Mg-ally, power ratio is Al alloy=1.3 to cast iron = 3.5) It has low inertia force in cutting and has advantage in starting and stopping machine due to low specific gravity and has no effect for vibration. It has low heat increase of equipment by cutting heat due to excellent heat conduction. It is easy to handle machine due to light weight below a quarter of iron. It has high cutting efficiency due to high cutting speed. It is possible for dry cutting. Aluminum innovation Decrease friction coefficient up to the utmost limits by charging MOS₂ to alumite film sufficiently. Material of anti-abrasion working part with lubricating capacity. No needing oil supply. Keep capacity of close adhesion without peeling off. Remove weak point of existing film processing and MOS₂ application way like flaw and exfoliation. Hard lubricating alumite of ceramic property in high anti-corrosion.
