Magnesium is the lightest structural metal and exhibits excellent machinability. Some of the advantages of machining magnesium compared to other commonly used metals include: • Low power required – approximately 55% of that required for Al. • Fast machining – employing the use of high cutting speeds, large feed rates and greater depths of cut. • Excellent surface finish – extremely fine & smooth surface achieved. • Well broken chips – due to the free-cutting qualities of magnesium. • Reduced tool wear – leading to increased tool life. To fully exploit and enjoy the advantages of machining magnesium, it is important that the unique characteristics of the metal are understood.

The maximum extrusion speed depends on the alloy that’s been used and defines the price. The alloy AZ 31 is easier for extrusion, and the most difficult alloys are for example AZ 80 and ZK 60 The extrusion speed is sometimes more than ten times slower for these alloys.   We comply with the specifications: GB5153-03, GB5154-04, AMS4377G, ASTM B90/B90M-15, MIL-DTL 32333, MIL-T-38749, QQ-M-44B, ASTM B107/B107M-13 and ASTM B91-97 Material grades: AZ31B, AZ61A, AZ80A, AZ91D, AZ41M, ZK60, AM50, AM60, ZM21, MIA, ME20M, EQ21, WE43, WE54, ZE41, etc.   Our main products and capabilities are as follows: 1.

TAPPING Standard taps are suitable for small production quantities or if high tolerances are not required. For best results taps tailored to magnesium should be used. Taps should be provided with large polished flutes. HSS two flute taps with ground threads are recommended for diameters less than 4.8 mm, three flute taps for diameters up to 19mm. and four flute taps for diameters over 19mm. Taps should be ground to be concentric with the front lead or cutting portion having a clearance of about 20°. Where there is no form relief, all lands should be hooked on both sides to give a leading top rake of about 10° for entering and about 5° for backing out where required (see figure 6). When tapping holes 0.25mm diameter and smaller the operation may be done dry. Mineral oil lubricants should be used to increase tap life, increase the accuracy of threads, improve the surface finish, or if chip jamming becomes a problem.

MgLi alloy is the most light weight metal structure materials, density is generally 1.35-1.65g/cm3, has a high specific strength and specific stiffness and excellent damping performance and resistance to high-energy particle penetration. We also believed that the MgLi alloys will be widely used for aerospace, aviation, weapon, defense, nuclear industry and other potential industry sectors.
