Abstract
The present disclosure provides a manufacturing method of an aluminum alloy composition. The manufacturing method includes the following steps in the sequence set forth: (S1) providing an aluminum master alloy, wherein the aluminum master alloy comprises aluminum and copper; (S2) adding chromium to the aluminum master alloy and performing a first melting; (S3) adding a tantalum-chromium alloy and performing a second melting; and (S4) adding silver and performing a third melting to form the aluminum alloy composition.
Claims18
A manufacturing method of an aluminum alloy composition, comprising the following steps in the sequence set forth:
- (S1) providing an aluminum master alloy, wherein the aluminum master alloy comprises aluminum and copper;
- (S2) adding chromium to the aluminum master alloy and performing a first melting;
- (S3) adding a tantalum-chromium alloy and performing a second melting;
- and
- (S4) adding silver and performing a third melting to form the aluminum alloy composition.
An aluminum alloy composition comprising:
- 4.2 to 5.5 weight percent copper, 1.4 to 2.0 weight percent magnesium, 0.5 to 1.2 weight percent manganese, 0.05 to 1.0 weight percent silicon, 0.05 to 0.8 weight percent chromium, 0.01 to 0.5 weight percent tantalum, 0.01 to 0.5 weight percent silver and the balance of aluminum, wherein the chromium, a tantalum-chromium alloy and the silver are added sequentially by performing at least three times of melting.
