Wrought Magnesium Tooling Plate Lightweight Easily machined Non Magnetic China magnesium tooling plate

XYMCO’s key products - AZ31 magnesium tooling plate, AZ31-TP magnesium tooling plate, AZ31B-TP magnesium tooling plate, AZ31B-O magnesium tooling plate, AZ31B magnesium tooling plate, AZ31B-H24 magnesium tooling plate, AZ80A magnesium tooling plate, AZ91D magnesium tooling plate, AM50A magnesium tooling plate, AM60A magnesium tooling plate, purity magnesium tooling plate, which are produced from fine-grain magnesium alloys which is free from internal stresses. This material is internally stable, which assures minimum movement during machining. Tool & Jig plate is a machined product with flat surfaces and a surface finish equal to 32 micro-inches or better on both sides. It is readily machined with very little distortion.

Cast magnesium tooling plate is used where strength is not a requirement, but minimal machining distortion along with flatness is required. This material is non-heat treatable.
 
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.

MECHANICAL PROPERTIES

The sheet and plate shall conform to the tensile requirements in above Table unless other agreement is made between seller and purchaser. Mechanical Properties for sizes and tempers not shown in above Table shall be as agreed upon by seller and purchaser.
 
OTHER PROPERTIES
Typical Hadness
O temper: 67 Rockwell E
H24 temper: 83 Rockwell E
 
WELDABILITY
Excellent weldability with gas shielded arc using AZ61A (preferred) or AZ92A filler rod; post weld stress relief is required to prevent stress corrosion cracking. Resistance welding is excellent.
 
MACHINING
AZ31B, like all magnesium alloy sheet and plate, machines faster than any other metal. Providing the geometry of the part allows, the limiting factor is the power and speed of the machine rather than the quality of the tool material. The power required per cubic centimeter of metal removed varies from 9 to 14 watts per minute depending on machining operation.
 
DENT RESISTANCE
Weight for weight, AZ31B-H24 has proven to be superior to competitive materials in its resistance to denting at moderate energy levels.
Dent Resistance of 1mm Gauge Sheet (Dent depth in mm from 25mm spherical redius indentor on 350mm span)
 

 
SURFACE TREATMENT
All the normal chromating, anodizing, plating, and finishing treatment are readily applicable. AZ31B also responds well to plasma electrolytic oxidation finishing.
 
CORROSION RESISTANCE
Continuous exposure for 2.5 years.
