The development of zinc alloy Ⅲ

In the early 1970s, the Norand Mines Limied Research Center in Canada collaborated with Zastern in the United States to develop zinc-based long-s metal antifriction alloys ZA8, ZA12, ZA27, etc., and applied ZA27 antifriction alloys to rolling mills, presses, Low-speed, heavy-duty work situations such as gearboxes, coal mills, air conditioners, and precision machine tools have completely replaced traditional copper-based alloy antifriction materials.

The advent of a new generation of long-s metal antifriction alloys has received great attention from users all over the world. Many industrialized countries have invested more manpower and material resources in long-s metal R&D. There are dozens of companies in the United States. Long-s metal aluminum-based, zinc-based and other anti-friction alloys.

Because long-s metal has excellent friction reduction and good economical efficiency, it has been rapidly promoted in the manufacturing field and has completely replaced traditional anti-friction alloys such as copper-based alloys and babbitt alloys, and has strong market competitiveness.

Later, long-s metal bearing alloys were called new antifriction alloys.

In the article “LONG-S PLAN”, Zastern’s technical consultant Mr. Bess pointed out that the purpose of developing economical long-s metal zinc-based alloys is not only to replace them in the case where traditional bearing alloys can do it, but also It is important to apply long-s metal to copper-based alloys and babbitt alloys where the strength and wear resistance are not satisfactory.

According to the prediction of Mr. Bess at the time: “The long-s metal zinc-based alloy will have a great development in the near future, and its production scale and sales market will expand rapidly. The 21st century will be a long-s metal zinc-based alloy. The heyday.”
