Chromium

The chromium metal has the atomic symbol Cr and its atomic mass is 51,996 g/mol. It is mostly known for its use in chromium plating (which is often referred to simply as 'chrome'), but in fact its largest use is as an ingredient in stainless steels. Both applications benefit from its hardness, resistance to corrosion, and ability to be polished for a lustrous appearance.

Siman Ltd can offer the below mentioned chromium based chemicals:

Nickel

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant. Historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish. We can offer you the following products based on Nickel:

Copper

Copper was one of the first metals to be worked into implements and the first metal to be smelted from ores. Its colour is copper-red and changes to black or green in air. Its name stems from Greek- "kyprios", of Cyprus, where the ancient copper mines were. Its Latin name is “cuprum”.

Siman Ltd can offer the following copper based materials:

Tin

Tin is a soft, silvery-white metal that is very light and easy to melt. Being so soft, tin is rarely used as a pure metal; instead, it is combined with other metals in order to make alloys that possess tin's numerous beneficial properties. As tin has good chemical resistance, it is used as a coating of other metals to prevent corrosion, the coating of steel to produce tin plate being an important example of this application.

Siman Ltd can offer the following tin based chemicals:

Selenium

Selenium is a non metallic chemical element, member of the group XVI of the periodic table.Its atomic number is 34 and it has a mass of 78.96 g/mol. One of its main usages is in in electronics, such as photocells, light meters and solar cells, for selenium has good photovoltaic and photoconductive properties. The second largest use of selenium is in the glass industry: it is used to remove colour from glass, to give a red colour to glasses and enamels. The third min use, taking about 14% is sodium selenite for animal feeds and food supplements.

Siman Ltd can offer the below listed selenium based products:

Molybdenum

Molybdenum is a silvery-white metal that is ductile and highly resistant to corrosion. It has one of the highest melting points of all pure elements. Scheele discovered it in 1778. Molybdenum is also a micronutrient essential for life. Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades.

Siman Ltd can offer the following molybdenum-based chemicals:

Vanadium

Siman Ltd is committed to source and supply high performance vanadium products. Our full product series include vanadium oxides, vanadium compounds and vanadium electrolyte, which have wide applications in the field of aerospace, energy, chemical industry and other potential emerging markets.

Cadmium

Cadmium is a chemical element with symbol Cd and atomic number 48. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic. Cadmium is a common component of electric batteries, pigments, coatings and electroplating.

Siman Ltd can offer the below mentioned cadmium based chemicals:

Lithium

Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production, lithium batteries, and lithium-ion batteries. These uses consume more than three quarters of lithium production.

Siman LTD. could offer you lithium products listed below:

Antimony

The antimony is found in the sulfide mineral stibnite and has a silvery-gray color. Antimony has many uses: as an anti-emetic in the pharmaceutical, textile, enamel and paint industries, in the blast and military industries. The metal has a low toxic level, while the antimony vapors, if inhaled, are very harmful. Siman LTD can offer the following antimony compounds for glass and ceramics production and galvanic technology.

Zinc

Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. Zinc is most commonly used as an anti-corrosion agent and galvanization (coating of iron or steel) is the most familiar form. Zinc oxide is widely used as a white pigment in paints and as a catalyst in the manufacture of rubber to disburse heat.
