CNC Machining: What are the CNC Machining Materials You Know?

 

 

The main materials for CNC machining are as follows:

 

 

 

 

 

Aluminum alloy 6061

 

 

 

 

6061 aluminum alloy is a high-quality aluminum CNC machined part produced by heat treatment and pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, its magnesium and silicon alloy characteristics are more.

 

 

 

 

Material advantages:

 

 

It has excellent CNC machining performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness, no deformation after CNC machining, dense material without defects, easy to polish, easy to color film, and excellent oxidation effect.

Aluminum alloy 7075

 

 

7075 aluminum alloy is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 is one of the strongest alloys commercially available.

 

 

 

Material advantages:

 

 

Normal corrosion resistance, good mechanical properties and anodic reaction. The finer grains provide better deep drilling performance, enhanced tool wear resistance and differentiated thread rolling.

 

 

 

 

 

 

 

 

 

 

Copper

 

 

 

Pure copper (also known as red copper) is a ductile metal with excellent electrical conductivity with a rose-red surface. It is not pure copper, it contains 99.9% copper, and some other elements are added to improve the surface and performance.

 

 

 

 

Material advantages:

 

 

It has good electrical and thermal conductivity, ductility, deep drawability and corrosion resistance.

 

 

The electrical conductivity and thermal conductivity of red copper are second only to silver, and are widely used in the production of electrical and thermal conductivity equipment. Copper has good corrosion resistance in the atmosphere, seawater and some non-oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and various organic acids (acetic acid, citric acid), and is used in the chemical industry.

 

 

It has good weldability and can be processed into various semi-finished products and finished products by cold and thermoplastic CNC machining. In the 1970s, the output of red copper exceeded the total output of other types of copper alloys.

 

 

 

 

 

 

 

 

 

Brass

 

 

Brass is a copper-zinc alloy, and brass composed of copper and zinc is called ordinary brass.

 

 

 

 

Material advantages:

 

 

It has high strength, high hardness and strong chemical resistance. There are also outstanding mechanical properties of cutting CNC machining.

 

 

Brass has strong wear resistance. Special brass is also called special brass, which has high strength, high hardness and strong chemical corrosion resistance. There are also outstanding mechanical properties of cutting CNC machining. The seamless copper tube drawn from brass is soft and wear-resistant.

 

 

 

 

 

 

 

 

45 Gauge Steel

 

 

45 steel is the name in GB, also called "oil steel". This steel has high strength and good CNC machining.

 

 

 

Material advantages:

 

 

It has high strength and good machinability. After proper heat treatment, certain toughness, plasticity and wear resistance can be obtained. The material source is convenient and suitable for hydrogen welding and argon arc welding.

 

 

 

 

 

 

 

 

40Cr Steel Introduction

 

 

40Cr is the standard steel grade of GB in my country, and 40Cr steel is one of the most widely used steels in the machinery manufacturing industry.

 

 

 

Material advantages:

 

 

It has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of the steel is good. In addition to the quenching and tempering treatment, the steel is also suitable for cyanidation and high-frequency quenching. Good cutting performance.

 

 

 

 

 

Q235 steel Introduction

 

 

Q235 steel is a carbon structural steel, and the Q in its steel number stands for yield strength. Normally, the steel is used directly without heat treatment.

 

 

 

 

Material advantages:

 

 

As the thickness of the material increases, its yield value decreases. Due to the moderate carbon content, the comprehensive performance is good, and the strength, plasticity and welding properties are well matched, and it is the most widely used.

 

 

 

 

 

SUS304 Steel

 

 

SUS304 refers to 304 stainless steel, which has the characteristics of good CNC machining performance and high toughness.

 

 

 

 

Material advantages:

 

 

It has good corrosion resistance, heat resistance, corrosion resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening phenomenon, no magnetism.
