Silicon Nitride Ceramic Plunger:
Silicon Nitride Ceramics is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a variety of alloys composed of two or more elements, it is called special brass. Brass has strong wear resistance. Brass is often used to make valves, water pipes, connecting pipes for internal and external air conditioners, and radiators. So far, the earliest copper products found in the world are mainly in West Asia, such as the Jawi Chemi area of Iraq. Copper ornaments were found, dating from about 10,000 BC to 9,000 BC; Ali in western Iran ·Bronze ornaments have also been found in Kashgar, dating from 9000 BC to 7000 BC; copper needles and copper cones were unearthed at the Chayoni site in southern Turkey, dating from about 8000 BC. These silicon nitrides are all made of natural red copper, not copper obtained by smelting ores. From the use of pure copper, to the smelting of copper ore to obtain pure copper, to the smelting of bronze alloys, mankind has experienced a long period of exploration. It is like using copper to create a sparkling time and space in a magical world. tunnel. The earliest copper smelting in the world was discovered in Shaanxi, China. In 1973, a semi-circular brass sheet and a brass tube were discovered in the Jiangzhai Cultural Site in Lintong, Shaanxi, dating to around 4700 BC. It is worth pointing out that recently at Shanghai Light Source, using X-ray fluorescence surface scanning analysis, it was found that there are significant differences in the zinc content in different areas of the Jiangzhai brass sheet, while the lead element is scattered in dots. Its characteristics are similar to those prepared by solid-state reduction. Brass is exactly the same, which proves that the ancestors used hot forging or solid reduction to smelt metals when they used natural metal and invented metal for casting.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
