What is Copper?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Copper which has developed particularly rapidly in recent years. Do you know about Copper?

The official answer: Cuprum is a metallic element and also a transitional element, the chemical symbol Cu, the English copper, atomic number 29. Pure copper is a soft metal, the surface is reddish-orange with a metallic luster when cut, and the element is purple-red. Good ductility, high thermal and electrical conductivity, so cables and electrical and electronic components are the most used materials, can also be used as building materials, can be composed of many kinds of alloys. Copper alloys have excellent mechanical properties and low resistivity, the most important of which are bronze and brass. Too, copper is a durable metal that can be recovered many times without compromising its mechanical properties.
Divalent copper salts are the most common copper compounds, their hydrated ions are often blue, while chlorine as a ligand is green, is a source of mineral colors such as azurite and turquoise, and has been used as a pigment. Copper building structures produce patina (basic copper carbonate) after corrosion. Decorative arts use metallic copper and copper-containing pigments.
Copper is one of the earliest metals used by humans. As early as prehistoric times, people began to mine open-pit copper and use the copper obtained to make weapons, tools and other utensils, and the use of copper had a profound impact on the progress of early human civilization. Copper is a metal found in the earth’s crust and oceans. The content of copper in the earth’s crust is about 0.01%, and in individual copper deposits, the content of copper can reach 3% to 5%. Most of the copper in nature exists as compounds, copper ores.
Copper is less active, and the reaction of iron element with copper sulfate can replace the copper element. Copper elemental insoluble in non-oxidizing acids.

What’s the application of Copper?

Electrical and electronics markets Transportation equipment Industrial machinery and equipmentalloy
Copper can be used to make a variety of alloys, and the important alloys for copper are as follows:
(1) Brass: Brass is an alloy of copper and zinc, named after the yellow color. Brass has good mechanical properties and wear resistance, and can be used to manufacture precision instruments, parts of ships, shell casings of guns, etc. Brass sounds good when it sounds good, so instruments such as gongs, cymbals, bells, and trumpets are made of brass.
(2) Nautical brass: alloy of copper, zinc and tin, resistant to seawater erosion, can be used to make ship parts, balancers.
(3) Bronze: The alloy of copper and tin is called bronze, which is named because of the color blue. In ancient times, alloys were used (such as the Bronze Age in China). Bronze generally has good corrosion resistance, wear resistance, casting and excellent mechanical properties. It is used for the manufacture of precision bearings, high-pressure bearings, mechanical parts on ships that are resistant to seawater corrosion, and various plates, pipes, rods, etc. Bronze also has an anomalous property – “heat contraction and cold expansion”, which is used to cast statues, which are cooled and expanded, which can make the eyebrows clearer.
(4) Phosphor bronze: alloy of copper and tin and phosphorus, hard, can make springs.
(5) White copper: white copper is an alloy of copper and nickel, its color is the same as silver, silver is shining, not easy to rust. used in the manufacture of coins, appliances, gauges and ornaments.
(6) 18K gold (rose gold): alloy of 6/24 copper and 18/24 gold. Reddish yellow, hardness, can be used to make jewelry, ornaments.

WHY THEY SAY TO US

United Kingdom Giles

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
