Blastany pitches copper slag as a cheaper alternative for industrial blasting

Jinan Junda Industrial Technology Co., Ltd, which operates as Blastany, is positioning its copper slag as a high-performance abrasive for shipbuilding, steel fabrication and other heavy industries. The company says the material can reduce dust, improve safety and lower project costs compared with quartz sand, garnet and steel grit.

Why it matters: - Surface-preparation contractors are weighing blasting speed, safety compliance and total project cost at the same time. - Blastany is targeting open-air industrial jobs where media recovery is impractical and abrasive choice can affect labor, equipment and waste costs. - The company frames copper slag as a lower-risk alternative to quartz sand and a lower-cost option than garnet or recovery-heavy steel grit.

What happened: - Jinan Junda Industrial Technology Co., Ltd, which uses the Blastany brand, published a product and comparison overview on November 3, 2026. - The company said its copper slag is made from refined metallurgical byproducts through crushing and multi-stage screening. - Blastany directed customers to its official portal for product access, samples and technical assessments.

The details: - Blastany says its copper slag has a density of 3.85 grams per cubic centimeter and a bulk density of 3.98 grams per cubic centimeter. - The material carries a Mohs hardness rating of 7. - Blastany says moisture content is controlled at 0.18%. - The abrasive contains minimal chloride ions and no loose silica. - Available mesh sizes include 6–10, 10–20 and 20–40. - Blastany says the material generates less dust than ordinary silica sand and produces a strong anchor profile for protective coatings. - The company says the abrasive can help remove mill scale, weathered layers and industrial coatings quickly. - Blastany says the media can help users reach SSPC-SP 5 or SSPC-SP 10 white metal cleanliness standards. - The company says partial reuse is possible in some environments. - Blastany says the abrasive is suited to structural steel, bridge girders, marine vessels and oil storage tanks. - The company says it helps project engineers match mesh size to cleanliness grades such as Sa 2.5 or Sa 3.

Between the lines: - The positioning is aimed at contractors that want a single-use abrasive without investing in recovery or containment systems. - Blastany is trying to differentiate copper slag on economics, not just performance. - The comparison underscores a broader industry tradeoff: cheaper disposables can be more practical for field work, while higher-recovery media can make sense in controlled indoor settings. - The company’s safety argument centers on free-silica avoidance, which matters in regions that restrict quartz sand use.

What's next: - Blastany says industrial users can request material samples and technical assessments through its website. - The company is seeking adoption from contractors managing large-scale maintenance jobs that need consistent blasting media at lower per-ton cost. - Future purchasing decisions will likely hinge on whether the abrasive delivers the expected surface profile, coating adhesion and budget savings on specific substrates.

The bottom line: - Blastany is betting that copper slag will win in field applications where speed, safety and lower upfront cost matter more than maximum reuse.
