Introducing commonly used cymbals

1. Cold rolled ordinary thin steel sheet is the abbreviation of ordinary cold rolled structural carbon steel sheet, because room temperature rolling does not produce scale, so the surface quality is good, dimensional accuracy is high, combined with annealing processing, its mechanical properties and process performance are good, this is the most common used metal material for sheet metal processing.

Common grades: National GB standard (Q195, Q215, Q235, Q275), Japanese JIS standard (SPCC, SPCD, SPCE)

2. Continuous electro-galvanizing thin steel plate, commonly known as electrolytic plate, refers to the deposition of zinc from deep sea zinc salt on the surface of a pre-prepared cold plate under the action of an electric field. a galvanized layer will be formed on the electro-galvanizing line and on the surface of the steel sheet, which gives the steel sheet good corrosion resistance.

Class: UK National Standard (DX1, DX2, DX3, DX4), Japanese JIS Standard (SECC, SECD, SECE)

3. Continuous hot dip galvanized thin steel sheet, commonly referred to as galvanized sheet or white iron sheet. It also has good welding and cold forming characteristics. Compared to the surface of a galvanized sheet, its coating is thicker. , and it is mainly used for sheet metal parts which require high corrosion resistance.

Grade: National GB Standard (Zn100-PT, Zn200-SC, Zn275-JY), Japanese JIS Standard (SGCC, SGCD1, SGCD2, SGCD3)

4. Stainless steel plate resistant to mild aggressive media such as air, steam, water and chemicals such as acids, alkalis and salts.

Steel that corrodes in aggressive environments is also called acid-resistant stainless steel. In practical applications, mild corrosion resistant steel is often referred to as stainless steel, and chemical corrosion resistant steel is referred to as acid resistant steel.

Stainless steel is usually divided into:

1. Ferritic stainless steel. Chromium from 12% to 30%. Its corrosion resistance, toughness and weldability increase with increasing chromium content, and its chloride stress corrosion resistance is better than other types of stainless steel.

2. Austenitic stainless steel. It contains more than 18% chromium, and also contains about 8% nickel and a small amount of molybdenum, titanium,

Nitrogen and other elements. Good overall performance, corrosion resistance in various environments.

3. Austenitic ferritic duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steels and has superplasticity.

4. Martensitic stainless steel. High strength, but poor ductility and weldability.

It should be noted that: the strength of stainless steel sheet is high, and the tool wear of CNC punching machine is relatively large, generally not

Suitable for digital punching.

Grade: There are many types of stainless steel, and austenitic stainless steel is commonly used in sheet metal processing.

5. Aluminum plate, aluminum is a silver-white light metal with good thermal conductivity, electrical conductivity and ductility.

Pure aluminum has very low strength and cannot be used as a structural material. Aluminum alloy plates are commonly used in sheet metal processing. According to the content of alloying elements, aluminum plates can be divided into 8 series, namely 1000 series, 2000 series ~ 8000 series, 2000 series, 3000 series and 5000 series are commonly used. -Aluminum alloy with good corrosion resistance, so it is also called rust-resistant aluminum, 5000 series is a magnesium-aluminum alloy, featuring low density, high tensile strength and high elongation. With the same area, the weight of aluminum-magnesium alloy is lower than other series.

Commonly used brands: 3A21 (old brand LF21), 5A02 (old brand LF2), 2A06 (old brand LY6)

6. Red copper plate. Red copper is the general name for pure copper with a purple hue, excellent electrical conductivity, thermal conductivity and durability.

Expandable and corrosion resistant but expensive, mainly used as conductive and heat conductive materials, commonly used for parts that need to carry high currents in power sourcespower, copper has low strength and, as a rule, cannot be used as structural parts.

Class: T1﹑T2﹑T3

7. Brass sheet, brass is a copper-zinc alloy with high strength and excellent cold and hot workability, but

Easy to corrode and crack, relatively cheap and widely used.

Common grades: H59﹑H62﹑H70
