Master Alloys

Alloy nna ukwu bụ metal ntọala dị ka aluminium, magnesium, nickel, ma ọ bụ ọla kọpa jikọtara ya na pasentị dị elu nke otu ma ọ bụ abụọ ihe ndị ọzọ. A na-emepụta ya ka ọ bụrụ akụrụngwa site na ụlọ ọrụ ọla, ya mere anyị ji kpọọ master alloy ma ọ bụ ngwaahịa alloy nke emechara. A na-emepụta alloys Master n'ụdị dị iche iche dị ka ingot, efere waffle, mkpara na eriri igwe na wdg.

1. Gịnị bụ master alloys?
Alloy nna ukwu bụ ihe alloy a na-eji maka nkedo nwere kpọmkwem ihe mejupụtara ya site na nchacha ya, yabụ a na-akpọkwa alloy master alloy ihe nkedo. Ihe mere eji na-akpọ nna ukwu alloy "nna ukwu alloy" bụ n'ihi na o nwere ike mkpụrụ ndụ ihe nketa Njirimara dị ka isi ihe nke nkedo, ya bụ, ọtụtụ àgwà nke nna ukwu alloy (dị ka carbide nkesa, ọka size, microscopic mirror image Ọdịdị. ), Ọbụlagodi gụnyere akụrụngwa akụrụngwa na ọtụtụ njirimara ndị ọzọ na-emetụta ogo ngwaahịa nkedo) ga-eketa nkedo mgbe agbazechara na wụsa.
