Brass Ingot Desofin Promoter For Metallurgy Industry Sodium Free
Desofin grain refiner is the chemical powder for metallurgy industry invented by Richard H. Haupt.
Mr. Haupt, born in America,engages in brass permanent molding industry in all his life till now.
He discovered several metallurgical chemical powders. Among them, I75L mold-release agent was invented in year 1976 while Desofin grain refiner was invented in year 1982.
These inventions converges his valuable practice and experience of more than 50 years in this industry.
The belowing table is what we suggested alloy class and dosage when adding Desofin.
