![]() ![]() Q: Can I get a sample of the product before signing the contract?Ī: 1kg sample can be used for quality inspection and market test. Alloys of zirconium (often referred to as Zircaloys), used in nuclear reactors, also often contain a small amount of tin. Tin alloys can also be found in a wide variety of other applications, including Babbitt bearings (often alloyed with copper, lead or antimony), automobile parts (alloyed with iron), dental amalgams (alloyed with silver) and aerospace metals (alloyed with aluminum and titanium). Used in various purities and alloys (often with lead or indium), tin solders have a low melting point, which makes them suitable for bonding materials. Tin's modern application is as a solder for the electronics industry. Tin and sulfur compounds - tin sulfide, which is similar in color to gold, is commonly used as a gold pigment. Metal tin is mainly used in the manufacture of alloys. Therefore, people often identify whether a piece of metal is tin or not based on this property of tin. Strangely enough, if an alloy of tin is used instead, it does not make this crying sound when it is deformed. Such friction occurs when the crystals are deformed. This sound is caused by the friction emitted between the crystals. Pure tin has a peculiar property: when tin rods and plates are bent, they make a special bursting sound as if they were crying. Tin is also a low melting point metal, its melting point is only 232☌, so it can be melted into a liquid with good fluidity just by using a candle flame. ![]() It has good ductility, especially at a temperature of 100☌, and can be spread into very thin tin foil, which can be as thin as 0.04 mm or less in thickness. Its hardness is relatively low, and you can cut it with a knife. Tin is a silvery-white and soft metal, which is very similar to lead and zinc, but looks brighter. Properties: Silver-white metal, soft, with good ductility. ![]() Relatively speaking, the larger the number, the higher the structure.Each ingot is 25kg. The second and third numbers, assigned by the American Society for Testing Materials' D24.41 committee on carbon black and terminology, reflect the varying degrees of structure, the approximate high and low structure of carbon black, and are somewhat arbitrary. The first number represents the surface area range of carbon black nitrogen, which is classified as 0 to 9 grades. ![]() The first English letter represents the vulcanization rate of rubber material, with N representing normal vulcanization rate, S representing slow vulcanization rate. In addition, factors such as vulcanization speed and structure of carbon black pigment were also taken into account in the naming, which consists of four systems. This classification is usually represented by three letters in English, the first two of which indicate the colouring capacity of carbon black and the last of which indicates the production method.Ĭarbon black for rubber - Carbon black for rubber was originally classified by particle size, but later changed to nitrogen surface area. According to different uses, carbon black is usually divided into pigment carbon black, rubber carbon black, conductive carbon black and special carbon black.Ĭarbon black for pigment - Internationally, according to the coloring ability of carbon black, it is usually divided into three categories, namely high pigment carbon black, medium pigment carbon black and low pigment carbon black. ![]()
