Cast Zinc Shot

 

Transmet Cast Zinc Shot
Transmet Cast Zinc Shot is a soft metallic shot for deburring, deflashing, and general blast cleaning and surface finishing of light metal castings and other non ferrous products. Cast Zinc Shot is also effective in blast cleaning rust and scale from iron castings and other ferrous parts without damage to part detail.

With a bulk density similar to steel, Cast Zinc Shot can deliver the energy for deburring and flash removal without leaving an aggressive surface profile. The resulting surface finish is very bright and evenly textured.

Cast Zinc Shot vs Other Blast Media

Transmet Cast Zinc Shot is manufactured to outlast other blast media and produce significantly less dust. ZA4 Cast Zinc Shot lasts 2X longer than Cast Stainless Steel, 3X longer than Zinc Cut Wire, and 4X longer than Cast Steel Shot.

Graph to compare differences in durability and dust between blast media: Cast Zinc Shot, Cast Aluminum Shot, Cast Stainless Steel, Zinc Cut Wire, and Cast Steel Shot.

 

Applications for Cast Zinc Shot

Transmet Cast Zinc Shot can be used in air blast and centrifugal wheel blast equipment.

  • Removing paint, powder coat, e-coat, etc.
  • Surface preparation for painting or coating
  • Surface finishing non-ferrous components
  • Removing ceramic from investment castings
  • Descaling and rust removal remanufactured parts

Eliminate Shot Blasting Machine Wear

Transmet Cast Zinc Shot significantly reduces damage and wear on high-wear internal components like the impeller, control cage, wheel liners, blast wheel and blades. Cabinet wear as a whole is virtually eliminated.

This blast wheel has over 17000 hours of blasting with Transmet Cast Zinc Shot without damage:

Two Alloys of Cast Zinc Shot

The ZA4 alloy is the most popular and most aggressive form of Transmet Cast Zinc Shot. It has a greatly increased durability over the HG alloy. The ZA4 alloy will last up to 300% longer than zinc cut wire in blast cleaning operations.

Product Name S.A.E. Equivalent Cut Wire Equivalent Typical Shot Diameter (Inches/Microns) Harness Knoop
RSZ-500 ZA4 S-170 .020″ .019/500 91
RSZ-750 ZA4 S-230 .030″ .029/750 91
RSZ-850 ZA4 S-280 .040″ .033/850 91

The HG alloy is made from High Grade Zinc. This alloy is similar in hardness to zinc cut wire and imparts an equivalent surface finish on castings. The HG alloy lasts up to 50% longer than zinc cut wire in blast cleaning operations.

Product Name S.A.E. Equivalent Cut Wire Equivalent Typical Shot Diameter (Inches/Microns) Harness Knoop
RSZ-500 HG S-170 .020″ .019/500 68
RSZ-750 HG S-230 .030″ .029/750 68
RSZ-850 HG S-280 .040″ .033/850 68

Standard packaging for HG and ZA4 zinc products is 25 lb. bags.
