CNC Machining Brass and Copper Parts

CNC Machining Brass and Cooper Parts

In the modern CNC machining industry, CNC machining brass and copper parts have always been the most popular. Copper is the most friendly processing material in CNC machining. Brass is a kind of copper alloy with zinc as the main additive element, presenting the beautiful yellow color.

The proportions of zinc and copper can be varied to create a range of brasses with varying properties. Brass has higher malleability than bronze or zinc. Brass is a kind of copper alloy with zinc as the main additive element, presenting the beautiful yellow color. It is one of the most-used materials in the world.

In CNC machining, Brass has several features like Low friction, excellent electrical conductivity, golden appearance. Brass is a metal alloy with good machinability and excellent electrical conductivity. Ideal for applications that require low friction, so it can be applied in Jets, Aerospace, Pipe Fittings, Jewelry, Architectural, Marine Hardware, and more industries.

Materials – CNC Machining Brass and Copper

CNC Machining Materials for Brass Parts

360 Brass is also known as Machinable Brass because it has the highest lead content of any brass alloy. This excellent machinability is accompanied by minimal tool wear. It can be used to manufacture various parts such as gears, locks, pipes, and trims.

CNC Machining Materials for Bronze Parts

932 Bearing Bronze is a high strength alloy with good wear and corrosion resistance due to its tin, iron, and zinc content. It is most commonly used in bearings, bushings, and thrust washers. 932 bronze is not heat treatable.

CNC Machining Materials for Copper Parts

The excellent thermal and electrical conductivity of 101 and 110 copper alloys makes them a natural choice for bus bars, wire connectors, and other electrical applications. 101 copper (also known as superconducting copper) is more conductive due to its high purity (99.99% copper) but is more cost-effective because 110 is easier to process.

110 Copper

The complete name of 110 copper is C11000, likewise known as electrolytic difficult copper (ECP). It has excellent electrical as well as thermal conductivity and also good processability.

Typically talking, Copper 110 includes 99.99% copper and also no oxygen, since trace amounts of oxygen are likely to trigger “hydrogen embrittlement” and also should not be made use of when heated up (eg high temperature > 370 ° C), however sometimes the oxygen material is much less rigid, the method Up to o.o4%. C110 copper is very easy to cold job and also has stricter limitations on impurities than other qualities.

C10100 Copper

C10100 copper is a steel with high ductility, high electrical as well as thermal conductivity, high impact strength, as well as low volatility under a high vacuum. And also under anoxic problems, 101 is unsusceptible to hydrogen embrittlement at heat.

Advantages of Our CNC Machining Brass Parts

  1. Has high strength, good plasticity, can withstand cold and hot pressure processing well, and has good welding and corrosion resistance. Used for condensation and heat dissipation pipes, siphon pipes, serpentine pipes, cooling equipment parts.
  2. It has very good plasticity and high strength, good cutting performance, is easy to weld, not stable to general corrosion, but easy to crack. It is one of the most widely used varieties of ordinary brass. Used for complex cold-drawn and deep-drawn parts, such as radiator shells, ducts, bellows, cartridge cases, gaskets, etc.
  3. The price is the cheapest, the strength and hardness are high and the plasticity is poor, but it can still withstand the pressure processing well in the hot state, the corrosion resistance in general, and the other properties are similar to H62. Used for general machine parts, welded parts, hot stamping, and hot-rolled parts.
  4. It has good mechanical properties, good plasticity in a hot state and good plasticity in a cold state, good machinability, easy brazing and welding, corrosion resistance, but easy to cause corrosion cracking. In addition, the price is cheap, and it is an ordinary brass variety that is used as a habitual offender.
  5. It has high strength, toughness, and good anti-friction properties. It has high corrosion resistance in the atmosphere and seawater, but has a tendency to corrode and crack, and has good plasticity under hot conditions. Used to make structural parts that work under friction and seawater corrosion conditions.
