Chem-Trend covers the widest range of applications of any release agent company in the world. What application can we help solve your problems in?

Chem-Trend has shop floor experience, and a range of products, that covers over two-dozen different molding, forming and casting operations. Which one are you involved in?

Brass and Copper

Brass is an alloy of copper and zinc with a nominal composition of about 60% copper and 40% zinc although different grades have quite different ratios. Lead, tin and aluminum are also used as alloying elements to give specific properties. Most alloys have a melting range of above 900°C (1650°F) which creates a major challenge for tooling. Since most organic release agents will decompose at such high die temperatures, filled lubricants containing graphite are commonly used.

Die casting of pure copper is gaining interest particularly for casting of rotors for electric motors. The melting point of copper is even higher than that of brass (more than 1000°C / 1800°F), so again graphite lubricants are typically used. Water-based materials impose significant thermal stresses on tool steels so waterless formulations are preferred.

Our long history of working along side our customers to solve their die casting production issues has helped us develop an extensive amount of knowledge and an impressive portfolio of products addressing the difficult challenges faced with each type of metal alloy and conditions found in high-pressure die casting.
