Pressure treatment	Suitable for all types of cold treatment.
Features of heat treatment	The plastic alloy in the annealed condition. Not susceptible to hot cracking during annealing or soldering.
Casting	Suitable for all kinds of casting, including casting the caste under the gem-setting. The presence of graphite in the casting is undesirable because it causes brittleness of the alloy. The presence of zinc makes the alloy increases fluidity and sharper than cadmium lowers the melting point.
