Zinc-based alloys entered the era of “microcrystalline alloys”Ⅱ

In 2005, the China Micro-Nano Technology Society was formally established, marking the beginning of China’s micro-nano application technology and standing on the same starting line with developed countries in meeting the individual needs of functional materials. Researchers from the China Micron Nanotechnology Society have applied micro/nano technology to the field of special antifriction alloy materials, […]


Zinc-based alloys entered the era of “microcrystalline alloys”Ⅰ

In July 1990, the first International Nano Science and Technology Conference was held in Baltimore, USA, marking the official birth of nanoscience and technology. The conference officially announced that nanomaterial science is a new branch of materials science. In 1999, nanotechnology went to the market, and the global annual turnover of nanotechnology-based products reached 50 […]


The development of domestic zinc alloy Ⅱ

In 1985, with the support of Ms. Chen Shuzhi, the deputy governor of Liaoning Province, and the relevant leadership of the Shenyang Foundry Research Institute, the Shenyang Bearing Material Research Institute, which is composed of the technical backbone of the Shenyang Foundry Research Institute, was established, specializing in the introduction of foreign countries. Long-s metal […]


The development of domestic zinc alloy Ⅰ

Because the new long-s metal zinc alloy and the traditional babbitt alloy can be used to manufacture sliding bearings, and the manufacturing cost is much lower than that of the Babbitt alloy, the long-s metal is transliterated into “Long’s alloy” in China. Long-s metal is a new antifriction alloy, and more people are used to […]


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 […]


The development of zinc alloy Ⅱ

In 1959, the International Lead and Zinc Organization member unit jointly launched a scientific research project named “LONG-S PLAN”, whose purpose is to develop a higher performance and longer service life than copper-based alloys and babbitt alloys. A new generation of antifriction alloys, the antifriction alloy in this development is called long-s metal in this […]


The development of zinc alloy Ⅰ

On the eve of the “World War II” in 1930, in order to solve the problem of copper resource shortage and high cost, Germany began to look for alternatives to tin bronze, lead brass and babbitt alloy, and launched a new generation of sliding bearing alloy research. In 1935, after nearly five years of research […]


Alloy classification

Zinc alloys, also known as zinc-based alloys, are generally classified into binary alloys, ternary alloys, and multicomponent alloys. Binary zinc-based alloys generally refer to zinc-aluminum alloys; ternary zinc-based alloys generally refer to zinc-aluminum-copper alloys; multi-component alloys generally refer to zinc-aluminum-copper and other trace metals. Zinc-based alloys, zinc alloys, zinc-aluminum alloys are a broad concept and […]


The role of one element in the alloy

Among the alloy components, effective alloying elements: aluminum, copper, magnesium; harmful impurity elements: lead, cadmium, tin, iron. (1) Aluminum effect: 1 Improve the casting properties of the alloy, increase the fluidity of the alloy, refine the grains, cause solid solution strengthening, and improve mechanical properties. 2 Reduce the ability of zinc to react with iron […]


Zinc alloy select

Which zinc alloy to choose, mainly considering three aspects The use of the die casting itself requires the performance requirements to be met. include: (1) Mechanical properties, tensile strength, is the maximum resistance when the material breaks; Elongation is a measure of material brittleness and plasticity; Hardness is the resistance of the surface of the […]
