What is Copper Alloy & What is it Used for
Ordinary pure copper is oxygen-containing copper with a copper mass fraction of not less than 99.7% and a very small amount of impurities, and its appearance is purple-red, so it is also called red copper. The main grades are T1, T2, T3.
Copper has poor high temperature oxidation resistance, and it is slowly oxidized at room temperature in the atmosphere. The corrosion rate in the atmosphere is 0.002~0.5mm/a, and the corrosion rate in seawater is 0.02~0.04mm/a. Copper has a high positive potential and maintains good corrosion resistance in non-oxidizing inorganic acid and organic acid media, but the corrosion rate is faster in ammonia, cyanide, mercury and oxidizing acid aqueous solutions.
Copper Alloy has excellent cold and hot working properties, and can be machined by various traditional pressure working processes, such as CNC machining, drawing, calendering, deep drawing, bending, precision pressing and spinning. During hot working, the atmosphere of the heating medium should be controlled to make it slightly oxidizing. The hot working temperature is 800~950℃.

Top Copper Cnc Machining Case Studies
Cnc Machining processes such as cnc milling, turning and swiss machining are today considered the most economic way to make copper prototypes. Sometimes, however, certain non-machiningable materials are needed, and sometimes 3d printing is the only option. Our company has rich experience making copper concept models and precise functional components. Understanding the properties of different copper alloy, with lots of testing and experimentation with pre-heating, tool paths and other factors, we are able to minimize deformation on copper alloy. Be-cu prototyping company provides a range of solutions for the machining of copper parts.
The Material Type Of CNC Machining Copper Alloy
Red copper is therefore also classified as copper alloys. Copper China cnc machining materials can be divided into: ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), adding a small amount of alloy Elements of special copper (arsenic copper, tellurium copper, silver copper) four categories. The electrical conductivity and thermal conductivity of red copper are second only to that of silver, and it is widely used in the production of electrical and thermal conductivity equipment. Red copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkalis, salt solutions and various organic acids (acetic acid, citric acid).
