Hailiang Group's two new products passed technical appraisal

The “HB-20 Lead Free Brass Rod (Environmentally Friendly)” and “HB-10 Durability” jointly developed by Zhejiang Keyu Metal Materials Co., Ltd. under the Hailiang Group and Hailiang Group Zhejiang Copper Processing Research Institute Co., Ltd. "Corrosion-resistant zinc-free green brass material" two new products have recently passed the appraisal of new products organized by Zhejiang Science and Technology Department. Both new products belong to the frontier high-tech materials in the world today. Among them, "HB-20 Lead Free Lead-free Brass Rod" uses HPb59-1 as the base alloy and replaces the harmful lead by adding germanium. The product not only has the good cutting performance of the common lead brass rod, but also meets the high requirement. Standard environmental protection requirements. “HB-10 Corrosion Resistant and Zinc-Resistant Green Brass” also uses HPb59-1 as the base alloy. By adding arsenic, it can suppress large area dezincification of brass and improve corrosion resistance. It can effectively inhibit the precipitation of lead and zinc, so as to meet the requirements of environmental protection. It is applicable to the plumbing and sanitary ware industry with higher environmental protection requirements. The two new products are innovative in material alloying design and casting technology, and the technology is at the leading domestic level.
