In magnesium alloys, what is the bentonite percentage composition?
View Answer Explanation
Copper alloys generally have sparking nature due to its high ductility.
Copper alloys have low thermal conductivity but high electrical conductivity.
In magnesium alloys, the water content in percentage is 10%.
Copper alloys possess good mechanical properties even at high temperatures.
At zero level temperature of copper alloys, they become very hard and brittle in nature.
Castings or components of copper alloys have high machinability and recyclability.
Foundry sands cannot be obtained in which of the following states?
In general, copper is highly reactive with sulphur and its chemical compounds.
Copper is generally a polymorphous material with body centered cubic (BCC) lattice structure.
It is very difficult to cast pure copper metal in mould cavity because of shrinkage problems.
