Sipxmach metal Brass/Copper Stamping parts or deep drawn parts, Serve all kinds industries in the world

Sipxmach metal stamping INC is an industry leader in precision stamping for Brass/copper parts. With over 10 years of experience and precision stainless steel stamping capabilities, we produce punching and blanking steel components that match your unique specifications.

Copper and copper alloys are well suited for stamping applications because of their corrosion resistance, high ductility. Often used for electrical and thermal applications, copper has an attractive patina finish that is appealing for consumer sectors, as well. Copper stamping parts now widely used on many industries: kitchen, appliance, electrical, telecommunication, connectors.

Brass/Copper stamping Blanks material Grades

We can produce deep drawn copper parts and prototypes in a wide range of material grades, including, but not limited to:

  • C11000 copper
  • C21000 copper
  • H61 Copper
  • H62 Brass
  • H59 Brass
  • Copper alloys
  • Etc. etc.

Copper has excellent electrical and thermal conductivity, and its conductivity and heat transfer coefficient are second only to silver and higher than all other metals. Copper is located in the IB family of the periodic table, and is associated with gold and silver. The elements of this group are characterized by good chemical stability. At the same time, copper and its alloys also have beautiful colors.

The application of copper revolves around its properties of conduction, heat transfer, corrosion resistance and color;
at the same time, copper has a special property that is seldom known to everyone: bacteriostatic properties. Copper sulphate (green) is added to the pool water, and a small amount of copper sulphate is added to the livestock feed to prevent bacterial growth and contact. The door handles of star hotels and hospitals are made of copper alloy, the purpose is to reduce the contact of bacteria.

Copper is not easily oxidized in the atmosphere, but a mixture of basic copper sulphate and basic copper carbonate (commonly known as patina) is slowly formed on the surface in moist air containing SO2 and CO2.
The patina is finely packed and tightly bonded to the copper matrix, thereby protecting the matrix from oxidation. Therefore, copper has good corrosion resistance in the atmosphere.
The ionization potential of copper in water is 0.52 (Cu), which does not react with H exchange electrons in water; only when it is oxidized to ionic state, copper reacts with H, so copper is resistant to corrosion in water. At the bottom of the China West Lake, the coins that were excavated thousands of years ago are intact. The copper pipes that have been used for a hundred years are still bright, which fully explains the problem.
Copper also has good resistance to chloride ion corrosion and is resistant to corrosion in seawater, which is unmatched by stainless steel.

Copper Metal Stamping Characteristics

The density of copper is 8.89 and the melting point is 1083 degrees. Its main characteristics are: good electrical conductivity, second only to silver in all kinds of metals, the purer the copper, the better the conductivity, the lower the resistance; the good thermal conductivity, second only to silver and in this respect. gold;

It has good corrosion resistance in the atmosphere, fresh water and sea water, so the copper water pipes and utensils can last for a long time; the plasticity is high, and it can withstand various cold and hot pressure processing well.

The disadvantage of copper is its low strength and hardness, which cannot be used as structural parts. Its main use in the industry is to manufacture wires and conductive parts for the electrical industry and to formulate various alloys. Pure copper can be divided into two major categories: smelting products and processing products.

Smelting products are smelted from copper ore by reduction, and are generally supplied in pellets and flakes. Pure copper processing products are divided into oxygen copper, oxygen-free copper, phosphorus deoxidized copper and silver copper. It is supplied in the form of semi-finished products of plates, rods, tubes and foils.

Since oxygen has an adverse effect on the mechanical properties and process properties of copper, especially when copper containing oxygen is heated in a reducing atmosphere, oxygen diffuses into the copper and forms water vapor with hydrogen, which rushes out of the copper at a certain pressure, causing Microcracking, commonly known as “hydrogen disease.” Therefore, copper for important electrical appliances generally uses oxygen-free copper.

Features and advantages of copper stamping parts include:

Because the Copper material have many above advantages, so many industries choose Brass/copper stamping parts with piecing, blanking, deep drawing to form required shapes and shapes. These Brass metal stamping products have following advantages:

  • Conductivity & heat resistance:
    Second only to silver, copper possesses superior thermal conductivity that makes it a staple for electrical, HVAC and gas tubing applications.
  • Finish:
    A beautiful “colored” metal, copper is often selected for architectural, design hardware and consumer goods applications.
  • Durability & corrosion resistance:
    Copper is non-reactive, and does not become brittle in sunlight or cold temperatures. It can also be alloyed with other metals to improve corrosion resistance in adverse environmental conditions.
  • Malleability and ductility:
    Copper’s high ductility and malleability after hardening makes it ideal for wiring, tubing, and other industrial purposes.
  • Sanitary:
    Copper is a naturally hygienic metal with antimicrobial properties, making it useful for the food & beverage industry.
  • Sustainability:
    Copper is highly recyclable without degradation or quality loss, so it is an attractive green option.

Sipxmach Brass/Copper Stamping and deep drawing Process

Brass/Copper sheet metal forming method typically is stamping and deep drawn. To create required shapes and dimensions. Deep drawn compare with stamping, the depth has special requirement. Our Copper stamping to do by mechanical presses and progressive dies, brass deep drawn to do by hydraulic machine. Deep drawn advance is seamless with high strength to avoid any welding flaws, but drawing shortages is only can form simple shapes.

Any holes that the part designs specify are punched into the part following the drawing process, and excess material is trimmed away.

Most brass stamping is “cold working process”, every step of deep drawing it will harden the material. But it softer than steel, aluminum and stainless steel, and copper material elongation better than these metals, so copper is an ideal deep drawing material.

Our experience and expertise enable us to produce any deep drawn copper part—from the simplest to the most complex—with exceptional precision. More intricate parts generally require more steps/dies in the stamping process, but can still be produced with the same speed and accuracy as more basic designs. And, deep drawn copper stamping is equally effective for prototype manufacturing and full production runs.
