Aluminum is one of the important engineering materials Non-ferrous metals in general because Aluminum has properties that can qualify the nature of the various components of the product or equipment engineering. The highly specific nature of the aluminum is a low specific gravity of only 2.702 Kg/dm3, possess high resistance to the effects of atmospheric corrosion and other properties are ...

Brass is an alloy of copper with more than 50% Zincum (zinc) is sometimes coupled with Tin (Tin) and Lead (Lead) and Aluminum and Silicon. Analysis of the equilibrium diagram of Copper-Zinc alloy (Copper-Zinc) showed that the alloy of Copper Zinc, Zinc levels above 37% is acceptable in the copper and will form a solid solution called (α). Copper Zinc ...

Copper-Nickel alloy is a metal that is a blend of the two elements of the element Copper (copper) to the Nickel. Metal alloys are divided into two kinds, namely: 1. Cupro-Nickel Namely metal with elements consisting of Copper and Nickel 2. Nickel Silver alloys namely between Copper (Copper), Nickel and Zinc (zinc). • Cupro-Nickel: Equilibrium diagram of Cooper-Nickel alloy (Figure ...

Formation by cold working (Cold Working) can also be done in a simple but if oversize desired size then it must first be softened (annealing) on the heating temperature 5000C. Cooling speed is not critical but Quenching with water to eliminate dirt and slag as well as ease in cleaning. a. Copper Alloy (Copper base Alloy) Copper Alloy (Copper base ...

The principles of hardening in Aluminium Alloys can be described as follows: a. Aluminium alloys with a total of up to 1% alloying elements consisting of Silicon, Manganese and Zinc iron in accordance with the desired properties, the maximum tensile strength can be achieved through the forging process (Forging) or various methods of cold working and the level of ductility ...

1. Bronzes and Gunmetals Bronzes are copper alloys and Gunmetals with white tin (Tin) as well as additional elements with little quantity consisting of Lead (lead). For all alloys Copper Lead is called the “Bronzes” and Copper alloys with tin called “Tin-Bronzes”, whereas with the addition of the element Zinc Bronzes called “Gunmetals”. Bronzes are very easily formed by casting ...
