Zinc Cast Shot

Transmet’s Cast Zinc Shot offers a gentle and efficient shot blasting process for light metal castings, providing painless paint removal and a bright finish. Its fine grain structure enhances durability and longevity, outlasting other blast media with minimal dust. This shot is prized for maintaining part appearance, cleaning fixtures, and removing coatings effectively without substrate damage.

It preserves delicate features, refines finishes evenly, and extends equipment lifespan while being less damaging than harder media. Cast Zinc Shot is ideal for surface finishing on aluminum, magnesium, and zinc, offering a smooth result. It is highly durable, outperforming steel shot and other abrasive materials significantly. This shot ensures blemish-free surfaces, prolongs machine lifespan, and protects internal components effectively.

ZA4 Alloy
The ZA4 alloy, the most popular and aggressive form of Transmet Cast Zinc Shot, offers significantly increased durability compared to the HG alloy. It outlasts zinc cut wire by up to 300% in blast cleaning operations, showcasing superior longevity. Custom-made to enhance cleaning ability and shot lifespan, ZA4 is a specially formulated zinc alloy designed for optimal performance.

HG Alloy
Crafted from High Grade Zinc, the HG alloy is softer than ZA4, making it a dependable choice for diverse applications. While being comparable in hardness to zinc cut wire and providing a similar surface finish on castings, HG lasts up to 50% longer than zinc cut wire in blast cleaning operations.
