Fiber laser cutting machine can be used for both plane cutting and bevel cutting, and the edges are neat and smooth. It is suitable for high-precision cutting processing such as metal plates. The materials that can be processed by laser cutting machines are: stainless steel, carbon steel, alloy Steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, galvanized sheet, pickling sheet, copper, silver, gold, titanium and other metal sheets and pipes cutting.

Laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting saves materials, smooth incision, and low processing cost. It will gradually improve or replace it. Traditional metal cutting process equipment.

So, what are the characteristics of copper alloys, brass, bronze and cupronickel that can be cut by laser cutting machines ? What are its fields of application? Lixing laser technical engineers will answer for you.

Analysis of the characteristics and application fields of copper alloy, brass, bronze and cupronickel for laser cutting materials:

The copper alloy of the laser cutting material has excellent material properties, and pure copper has good electrical conductivity, anti-magnetic properties, high thermal conductivity, an outstanding combination of strength and plasticity, and corrosion resistance in many environments.

Adding zinc to copper increases the strength of the alloy, as does its plasticity. 10-20% zinc alloys are known as gilded metals and are used in the jewelry industry and in the production of heat exchangers; 30% zinc alloys are known as cartridge brass. The maximum threshold for zinc in formable brass is about 35%. Adding other alloying elements can further improve the properties of brass. For example, tin and aluminum increase its corrosion resistance in seawater.

Brass for Laser Cutting Materials: Single Phase Brass Applications: Jewelry, Artwork, Tableware, Musical Instruments and Cartridges. Single-phase brass has a zinc content of up to 37%, known as alpha brass, has a uniform crystal structure, is softer, and is more ductile. Suitable for cold working, drawing, bending and other processes.

Duplex brass applications: heat exchangers, capacitors, parts made from automatic cutting tables, etc. Duplex brass contains both α and β phases, ie both α grain structure and β grain structure are present. Duplex brass is less expensive than single-phase brass due to the high amount of zinc used, and is also susceptible to corrosion. Its chemical composition gives it greater strength and hardness, making it suitable for processes such as thermoforming and casting.

Bronze is the laser cutting material. Bronze alloys are divided into different types according to the alloying elements used. Tin bronze application range: springs, washers, coins, handicrafts, pump parts, pressure-resistant castings, bearings, etc. Its application depends on the percentage of tin used in the alloy. The maximum content of tin in alloys suitable for cold working is about 7%, and copper alloys have good plasticity.

The main application of duplex tin bronze is in the bearing industry, this structure has a good balance, where the alpha phase ensures the impact resistance, while the hard and brittle compound carries the load and provides some wear resistance. Zinc and lead are also sometimes present in tin bronze. Zinc improved the quality of the castings and also made the alloy cheaper. This bronze was also known as gun bronze because large guns were made of this material in the past.

Aluminum Bronze Laser Cutting Materials Applications: Coins, Ship Parts, Ship Hardware, Sleeve Bearings, Pumps, Valves, etc. Aluminum bronze has similar properties to tin bronze, mostly single phase and suitable for cold forming, very suitable for making coins, where the aluminum content is usually between 6-12%. Duplex aluminum bronzes can be used as casting alloys or for hot working. Aluminum bronze, with an aluminum content of about 10%, is used to make propellers, valves, pumps, etc.

The scope of application of cupronickel for laser cutting materials: coins, marine equipment, electrical equipment, heat exchangers, cooling systems, shipbuilding, etc. Copper-nickel alloys are strong and highly malleable. The addition of nickel (typically 2-30%) to copper makes the metal highly corrosion resistant and has excellent electrical conductivity. Copper-nickel alloy has almost no coefficient of thermal expansion at 40…50% nickel, and the resistance is also the largest, so Constantan (Cu-Ni alloy with 45% nickel) is used for electrical equipment with large temperature changes. Corrosion-resistant copper-nickel alloys contain approximately 30% nickel, with small amounts of iron and manganese, and are particularly stable in salt water.
