Question

Monel metal chemical composition primarily by A = 70 percent and B = 30 percent approximately. A and B are ______ and ______, respectively.
1. Cu and Ni
2. Cu and Sn
3. Ni and Cu
4. Sn and Cu

Answer 1

Correct Answer - Option 3 : Ni and Cu

Explanation:

Mone metal:

• It is an important alloy of nickel and copper.
• It contains 68% nickel, 29% copper, and 3% other constituents like iron, manganese, silicon, and carbon.
• It is superior to brass and bronze in corrosion-resisting properties. 
• It is used for making propellers, pump, fittings, condenser tubes, steam turbine blades, seawater exposed parts, tanks, and chemical and food handling plants
• Small additions of aluminum and titanium, which form the K-500 alloy, increase strength, particularly at high temperatures, making it useful in aerospace applications.
• Monel alloys are most often found in chemical plant equipment due to their strong resistance to chemical corrosion.
• They are also used in the aerospace industry.
