Zinc shot :
Zn:99.99% Fe:0.004% Al:0.003% Cu:0.001% Cd:0.003%
Hardness:round shape: 45-60HV cut wire shot: 38-55HV
zinc shot are widely used for shot peening to give compressive
residual stress in the surface layer of components for fatigue life enhancement
and suppression of stress corrosion cracking and deburring and cleaning of zinc
or aluminum die cast parts without any damage to the parts, creating much less
dust than natural and artificial corundum abrasives.
