Dongguan Precision CastingHardware products are common things in our lives. Many places have their images. There are many things in hardware products. Hardware is only a kind. Many people may not know hardware. I know these are very helpful for my own choice. What are the types of hardware? Hardware refers to tools obtained through processing and casting of metals such as gold, silver, copper, iron, and tin, which are used to fix things, process things, and decorate. Everyone knows that gold is a very expensive metal material, one gram of several hundred yuan RMB, most of which is deposited in the national treasury by national government departments and stored very well. Most types are gold.
Gold pieces are of course used to make valuable items. Broken gold castings are generally used as jewelry, inflation, inflation and other objects, such as diamond rings, neck chains, gold coins (old gold coins), gold coins, etc. Silver Silver is silvery white, and it is also a precious metal. Following ancient China, silver ingots or silver ingots were used to carry out national expenditure and peacetime trading in ancient Egypt. The water-soluble silver ion sterilization effect of silver ions was used in ancient Egypt, causing silver flakes to be injured. Modern silver is also commonly used in jewelry processing. Silver has excellent electrical conductivity and heat transfer performance. Common industrial silver pieces are generally parts of electronic instruments and power generation equipment, such as silver core wires. Copper pieces Copper is the messenger of human civilization. Ancient people often used copper to make ritual vessels, such as copper tripods and modern tools. As we all know, copper has excellent electrical conductivity, second only to silver, but copper ore is more expensive and cheaper than silver ore. Copper is often used to make wire cores and some parts of communication equipment and electronic equipment. Iron is widely used and a lot of iron in the world today: the number of iron ore deposits discovered in the world has exceeded 200 billion cubic meters. There are two common types of iron: hematite and magnetite. Hematite red iron ore is mainly used for cast iron nails, screws, nuts, hammers, mechanical parts, etc. Magnetite is magnetic, also known as ferromagnet. Magnetite is not as wide as hematite and is also very useful. Tin parts are not widely used. Common tin parts include canned bottle caps, tin foil, and plastic bottle tin seals. Other hardware antimony parts: Antimony and lead can be mixed together to make bullets. Tungsten parts: mainly tungsten filaments. There is still a difference between hardware and hardware accessories. Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products. It can be used alone or as an aid. For example, hardware tools, hardware parts, daily-use hardware, construction hardware, and security products. Most small hardware products are not final consumer goods. Persistently used as auxiliary products, semi-finished products, special tools for production processes, etc. Only a small part of the usual hardware configuration products (notes) are necessary special tools for everyone's life.
