Platinum is one of noble metals, it is one of the best catalyst and antioxidants, nano platinum ( Pt ) with small particles size, strong, safe, stable, reliable, environmentally friendly, non-toxic, tasteless, harmless, can be widely used in biomedical, Catalytic industry, cosmetic etc.

nano-calcium carbonate

Submitted by admin on Wed, 08/14/2019 - 01:39

The most mature industry in which nano-calcium carbonate is applied is the plastics industry, which is mainly used in high-grade plastics products. It can improve the rheological property of plastic masterbatch and its formability. As a plastic filler, it can toughen and reinforce, improve the flexural strength and modulus of elasticity, thermal deformation temperature and dimensional stability of plastics, and at the same time give the plastics hysteresis.

Copper-nickel alloy

Submitted by admin on Tue, 08/13/2019 - 02:45

Copper-nickel alloy, copper and nickel are silver-white, with metallic luster, hence the name white copper.The strength, corrosion resistance, hardness, resistance and thermoelectric properties of pure copper and nickel can be significantly improved, and the temperature coefficient of resistivity can be reduced. Therefore, white copper has better mechanical and physical properties than other copper alloys, good ductility, high hardness, beautiful color, corrosion resistance and deep drawing properties.

Copper-silicon alloys

Submitted by admin on Wed, 08/07/2019 - 03:19

Copper-silicon alloys are alloys of copper and silicon. Usually 8% silicon is contained in the alloy, and a small amount of iron and manganese is added. It is easy to process and weld. Corrosion resistance, especially marine corrosion resistance. It is applied in the form of sheet, strip, bar and casting.Copper-silicon alloys are alloys of copper and silicon.

Arsenic (As) is a nitrogen group element in the fourth period of the periodic table of chemical elements. Arsenic is a non - metallic element widely distributed in nature.

rare earth element—erbium

Submitted by admin on Mon, 08/05/2019 - 01:38

Today Let's introduce an unusual rare earth element—erbium, which is a heavy rare earth element. It takes its name, like yttrium, from the town of Ytterby, near Stockholm, Sweden, where yttrium ore was first discovered. Almost all the rare earth Elements can be found in monazite and yttrium.Erbium is a silver-white metal that slowly oxidizes when exposed to air.

Nickel-copper alloys

Submitted by admin on Thu, 08/01/2019 - 02:39

Nickel-copper alloys are mostly used to make components, such as traveling wave tubes and magnetrons, which require high corrosion resistance, high temperature fatigue resistance and so on. Nickel-copper alloy is composed of 60% nickel, 33% copper and 6.5% iron.

High carbon ferrochrome

Submitted by admin on Wed, 07/31/2019 - 06:05

High carbon ferrochrome is natural block.  High chromium is assessed by 50% chromium content. Mainly used in stainless steel, the corrosion resistance of stainless steel mainly comes from chromium. Experiments show that only when the content of chromium exceeds 12%, the corrosion resistance of steel will be greatly improved. Therefore, the content of chromium in stainless steel is generally not less than 12%.
