Steel grade and chemical composition of high manganese cast steel
Introduction
High-manganese cast steel is a kind of low alloy cast steel with high strength, high toughness, good wear resistance and impact resistance after quenching and tempering. It is often used in situations of difficulty to heat treat steel or impact load and wear. At present, high-mangane......
Classification and grade of silver-based solder (GB 10064-88)
Classification and Grades of Silver Brazing Filler Metals
Silver Brazing is an excellent joining method for a wide range of materials, such as steels, stainless steels, nickel-base, titanium and aluminum alloys. Silver brazing filler metals or alloys are bonding materials used to join surfaces o......
Cast tin-based bearing alloy ingot
Introduction
Tin-based bearing alloy dingesare an important part of modern industrial ball bearing and roller bearing components. Compared with other bearing materials, tin-based bearing alloys have superior corrosion resistance, higher temperature fatigue life, good wear resistance and thermal c......
Gold plating method in Chinese and English
Electroplating (also known as galvanizing)
Electroplating (也称为镀金)是一种将某种金属以非常薄膜形式附着到另一种金属表面上的化学过程。这一过程使用电化学原理来实现。具体来说，当直流电在一个金属阴极和另一个金属阳极间通过电路时，通过溶解的阳极金属被移动到阴极的表面上，从而形成极薄的一层调节层。

bismuth
bismuth is a mineral that is commonly found in granites, pegmatites and other insoluble parts of igneous rocks. Native bismuth is a silvery-white metal that is brittle and often has a pinkish tinge when exposed to air. bismuth is the most diamagnetic element known and shows only a very weak respon......
Copper Concentrate Kneading
Metallurgical Copper Composite Compacting
Metallurgical copper composite compacting is a process for refining copper ore, in which a mixture of copper, zinc and sulfur is heated to a high temperature. The mixture then cools and is subjected to mechanical forming. In this process, the copper, zinc......
Rammelsberg mine
Ramelsberg Mining
The Ramelsberg mining area has a long and varied history, with mining of copper, silver, and gold stretching back more than 800 years. Mining in the area ensued first with surface mining, followed by open-pit mining, and finally, underground mining. This makes the Ramelsberg min......
bismuth smelting workshop design
bismuth Metallurgical Processing Workshop Design
bismuth is a pale, blue-white, brittle metal with a slightly pink tinge because of the residual traces of oxide it contains. bismuth has many properties, including being stable in air, acting as a less-corrosive substitute for lead, easy to form in......
Superconducting magnet manufacturing
Introduction
Superconductivity is a phenomenon of zero electrical resistance and perfect diamagnetism observed in certain materials at very low temperatures. Superconductors can be used to create unparalleled magnetic fields, and people use them in numerous ways. One of the most common applicati......
