Aluminum casting. Once the aluminum has been extracted and processed, the next step involves casting it into product form. Aluminum castings are formed by pouring molten metal into molds that have been shaped by a pattern of the desired final product.
Copper is an unreactive metal, it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota, USA and weighed over 400 tonnes. Native copper isn''t mined because there is so little ...
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...
excellent machining properties of these copperzinc alloys is so wellknown that they are often used as benchmarks for describing the machining properties of copper and copper alloys Machining copper alloys is considerably easier than machining steels or aluminium alloys of the same strength (see Figure 1).
