Zinc 60%

Zinc (Chinese pronunciation: xīn), its name 'zinc' is derived from the Latin Zincum, meaning 'white thin layer' or 'white sediment'. The chemical symbol is Zn, which has an atomic number of 30 and a relative atomic mass of 65. Zinc is a silvery whiteish light blue metal with a density of 7.14 g/cc and a melting point of 419.5 °C. At room temperature, the property is brittle; when it is 100 to 150 ° C, it becomes soft; after it exceeds 200 ° C, it becomes brittle. The chemical nature of zinc is active, and in the air at normal temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further oxidation. When the temperature reached 225 ° C, the zinc was violently oxidized.

Nickel Ni15% CU15%

Nickel Chinese name mu, English name: Nickel, element symbol is Ni, atomic number 28 in the periodic table, relative atomic mass 58.69, is a Group VIII metal. The density is 8.9 g/cm3, the melting point is 1455 ° C, and the boiling point is 2730 ° C. Nickel is a kind of silver-white metal. It is easily oxidized by air in the air, and some oxide film is formed on the surface. Therefore, the nickel that people see often has a black color. Nickel is hard, has good ductility, is magnetic and corrosion resistant, and is highly polished. Nickel is also very rich in the earth's crust. It exists in the form of nickel silicate or sulfur, arsenic, and nickel compounds in nature. Nickel is often used in the manufacture of stainless steel, alloy structural steel and other steel fields, electroplating, high nickel-based alloys and batteries, etc. It is widely used in various military manufacturing industries such as aircraft and radar, civil machinery manufacturing and electroplating ...

Tin tea set

Thai National Gift Tin Tea SetFirst of all, tin metal is a kind of green metal, which is harmless to the human body, and has good sterilization, purification, moisturizing and fresh-keeping effects. It is often used in food preservation paper, anti-corrosion film on the inner layer of cans, and materials for filling teeth; Secondly, there are many unique features of tin-made living utensils. The tin-made tea cans have good sealing properties and can maintain the color and aroma of the tea for a long time. The tin-made beer mugs have a rapid heat transfer, which makes the ice-cold beer multiply and widely used. Therefore, the tinware enjoys the reputation of “sweet water, sweet wine, mellow wine, unchanging tea flavor, long flower arrangement”.

Copper coil 30-60%

Features and scope of application: TP2 phosphorus deoxidized copper has good welding performance and cold bending performance. Generally, it has no tendency of 'hydrogen disease'. It can be processed and used in a reducing atmosphere, but it is not suitable for processing and use in an oxidizing atmosphere. TP1 has less residual phosphorus than TP2, so its conductivity and thermal conductivity are higher than TP2. TP1 and TP2 are mainly used for pipe applications, and can also be supplied by plates, belts or rods and wires. Used as gasoline or gas delivery pipe, drain pipe, condensing pipe, mine pipe, condenser, evaporator, heat exchanger, train box parts. TP2 phosphorus deoxidized copper chemical composition:Copper + silver Cu + Ag: ≥ 99.85Tin Sn: ≤0.01Lead Pb: ≤0.005Phosphorus P: 0.013 ~ 0.050Nickel Ni: ≤0.01Iron Fe: ≤ 0.05 (0.005)锑 Sb : ≤ 0.002Sulfur S : ≤ 0.005Arsenic As : ≤0.005铋 Bi: ≤ 0.002Oxygen O: ≤0.01Note: ≤0.15 (impurities) &...

Tin

Tin, a metallic element, a low-melting metal element with a silvery white luster, is divalent or tetravalent in the compound and is not oxidized by air, mainly by dioxide (cassiterite) and various sulfides ( For example, in the form of sulphurite. Element symbol Sn. Tin is a famous 'hardware' - one of gold, silver, copper, iron and tin. As early as ancient times, people discovered and used tin. In some ancient tombs in China, tin pots such as tin pots and tin candlesticks are often discovered. According to research, the use of tinware in China during the Zhou Dynasty has become very common. In the ancient tombs of Egypt, tin-made daily necessities were also found.
