The development of human civilization and the progress of society are very closely related to metallic materials. After the Stone Age, the Bronze Age and the Iron Age emerged. The application of metallic materials was a significant sign of their times. In modern times, a wide variety of metallic materials have become an important material basis for the development of human society. What are the main types of metallic materials? How do the properties of different metallic materials differ? Please follow SHANGYICHEN to learn!
Platinum is mainly produced in Russia, Colombia, South Africa and Canada. It exists on earth in a free state as a natural nugget, and in many cases platinum is symbiotic with gold and silver, and uranium gold is obtained when refining nickel and copper.
Platinum is off-white in color, does not oxidize, and can be made using casting, forging and welding processes. Platinum is extremely malleable and ductile. The melting temperature is very high, with a melting point of 1773°C. This is a very good feature, the maker can use the very high melting point of the welding section to weld without fear of melting the workpiece.
Gold is either panned from river sand in free form or present in quartz veins. Most gold is produced in South Africa, Russia and Canada.
Pure gold is soft, and in order to be worn and to show different colors, gold is usually used with other metals to make table gold.
Pure copper is slightly purplish red, so China's non-ferrous gold industry to its professional name as purple copper, some people also called red copper, easy to identify from the color. Unfortunately, copper is easy to darken and lose its luster, so the surface of copper na is often painted to play a protective role. Commercial steel purity of 999%, 01% for arsenic, arsenic makes copper hard. The melting point of copper is 1083°C. o Copper is an excellent conductor of electricity and heat, slightly inferior to silver.
SHANGYICHEN offers many forms of copper materials, welcome to buy!
Brass is a combination of zinc and copper. The zinc content is generally 5% to 40% o Different ratios can be used for different applications. Sometimes
Sometimes a small amount of copper or aluminum may be added for specific applications.
Commonly cast bronze contains 95% copper and 5% aluminum and is used for minting coins and casting bronze statues. The bell cast contains 80% copper and 20% tin and is used for casting bronze bells. Modern bronze has added phosphorus and aluminum to copper and aluminum, but is rarely used in the production of arts and crafts. Bronze is harder to the touch than pure copper when processed.
Aluminum is the most abundant metal in the earth's crust, and was first chemically decomposed in 1825, with commercial aluminum products appearing in 1886. Aluminum is a very light metal, the density is about 1/3 of copper, 1/4 of silver; melting point 660Y.
Aluminum has excellent electrical conductivity, and aluminum can be cast, forged, hammered and drawn. Aluminum can be riveted, fused and acetylene welded. Sulfuric acid and nitric acid cannot corrode aluminum, but hydrochloric acid and fire alkali can dissolve aluminum. Many aluminum combined all used in industry. Pure aluminum, a small amount of iron and pedantic combination will be used for handicraft.
SHANGYICHEN offers a wide range of aluminum metal materials in various forms.

What is the Advantage of Wire Mesh?
Wire mesh is a material made from interconnected metal wires. It is typically used as a barrier or filter in a wide range of applications, including fencing, construction, and industrial processes. Wire mesh can be made from a variety of metals, including steel, aluminum, and brass, and it can be produced in a variety of sizes and shapes, depending on the intended use. Some examples of wire mesh include welded wire mesh, woven wire mesh, and wire cloth.
