Magnesium engraving plate AZ31 magnesium sheet foil strip with good thermal conductivity

Why Magnesium Plate?

Magnesium CNC engraving plate has good carving processing performance. Because of its outstanding characteristics of magnesium plate engraving of low density, high specific stiffness, good damping property, environment friendly and no pollution, Recyclable good performance, known as the twenty-first Century green metal structure material.

The magnesium CNC engraving plate and mechanical processing of parts, in national defense, aerospace, electronic communication, rail transportation, medical equipment, printing plate, magnesium board carving mold and other fields, and has wide application prospect.

Magnesium CNC engraving plate as a kind of excellent metal material processing machinery and carving, has the following characteristics:

Cutting energy consumption with magnesium CNC engraving plate into 1, then 2.3 to 1.8 brass, aluminum, iron is 3.5; the cutting inertia is small it magnesium plate, can realize high speed cutting.

Magnesium CNC engraving plate, dimensional stability, not easy to change with temperature.

Non magnetic metal magnesium, magnesium plate shielding electromagnetic, strong anti-interference ability.

Magnesium has excellent damping properties, good damping.

Engraving magnesium board high specific stiffness. Magnesium the proportion of small, light weight.

Magnesium rich reserves of resources, recycling use.

Magnesium is widely exists in the nature, the magnesium CNC engraving plate can be naturally decomposed into magnesium salt, no harm to soil and water.

Magnesium CNC engraving plate adopts the carving process of high speed cutting has the following characteristics:

The feed speed engraving cutter can be improved more than 6 times; material removal rate can be increased by 5-6 times;

Magnesium aluminum plate surface roughness is greatly increased, up to 10 μ m

Generally, carving cutting resistance magnesium plate to reduce the 1/3;

Magnesium CNC engraving plate after hot deformation is low, can limit the work hardening;

Engraving tool durability increased nearly one times;

Magnesium CNC engraving plate processing time can be significantly reduced, directly led to reduced processing cost;

Cutting resistance magnesium plate of small, good thermal conductivity, heat quickly, so the cutting speed is very fast, very few sticky knives. Engraving and cutting tool life is long, and shortens the required tool replacement in the carving process downtime.

The chip formation in magnesium board carving process, associated with the shape of parts, alloy composition, feed speed and other factors. Because magnesium CNC engraving plate cutting, the chip integrity, continuous, general situation next finishing can meet the requirements of the carving surface roughness.

Magnesium engraving plate, AZ31 magnesium sheet polished surface with fine flatness, cut-to-size

AZ31B is a wrought magnesium base alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. Increased strength is obtained by strain hardening with a subsequent partial anneal (H24 and H26 tempers). Our sheet and plate’s size range is:

Sheet: thickness from 0.5mm to 6mm; Max. width is 600mm; Max. length is 6000mm;

Plate: thickness from 6 mm to 200mm; Max. width is 2000mm; Max. length is 6000mm;

Block: We can supply precut blocks according to customer’s requirements.

APPLICATIONS

Sheet and plate in AZ31B find application in medium strength service at temperatures below 150°C. Diverse uses including aerospace, aircraft, concrete tools, 3C (cell phone / camera / computer), speaker cones and textile machinery can all benefit from light weight AZ31B.

AZ31B is non-magnetic and has high electrical and thermal conductivity filling the requirements for RFI and EMI shielding in the electronics and computer industries.

Superplastic forming of AZ31B sheet at elevated temperatures allows production of a wide variety of intricate parts for automotive uses. Monocoque construction utilizing formed sheet can be adapted to many commercial applications.
