Xi'an XYMCO Magnesium Alloy Materials Co., Ltd. (XYMCO) provides the machining service for our customers according to their drawing. Magnesium has very good machining abilities like sawing, punching, drilling, milling, turning compared to other metals. The specific cutting power is low and the surface is excellent and the chips are short.

Magnesium is the fastest machining metal and it has a high thermal conductivity, advantages of it are for example:

* Long tool life, the tool stays sharp for long time

* Low power consumption, about 55% lower than for aluminium alloys

* Reduction of machining time because of the high speeds

* Short chips an excellent surface

Machineability

Relative power

Magnesium machining is normally without any coolant and when it is necessary to use coolant a light mineral oil suffices. Never use water based coolant because of the risk of any reaction with the chips during storage.

High – speed tools or carbide tipped tools are preferred for the machining of magnesium. It is important to keep the cutting tool sharp to avoid to much heat. The experience with diamond tools are excellent but the costs are relatively high. It is necessary to store machined products under dry conditions and when there is a chance of condensation, extra protection is needed.

Machines should be kept clean and the turnings should be stored in steel bins.

Products of magnesium will not ignite easily, the magnesium must be heated to the melting point and during normal machining that’s virtually impossible. The chips can be ignited but easy precautions should avoid this risk.

Magnesium dust howsoever has a high degree of flammability and these precautions are necessary to minimize these risk:

* Dry machining or use light mineral based oil

* Keep cutting tools sharp

* Dispatch the chips frequently and store these in steel closed containers

* Make sure there is an suitable extinguisher available

* Use compressed air with high speed automatic machining when shavings are produced

Should a fire occur, dry turnings will burn slow and evenly. Never use water to extinguish magnesium because the burning magnesium will decompose water to form hydrogen which is easily ignited.

The potassium chloride fire extinguisher powder is the best extinguisher; other common extinguishers are cast iron turnings and dry sand.

XYMCO has started to produce the forged magnesium alloy plate, forged magnesium alloy slab, forged magnesium alloy cube, forged magnesium alloy disc, forged magnesium alloy block and forged magnesium alloy billet from 2004.

ZK60A

ZK60A is a wrought magnesium base alloy containing zinc and zirconium. Increased strength is obtained by artificial aging from the as-fabricated form. ZK60A-T5 has the best combination of strength and ductility at room-temperature of the wrought magnesium alloys.

WELDABILITY

ZK60A is not considered to be weldable by conventional techniques due to hot-shortness cracking. However, resistance welding response is excellent. Friction stir welding can be used to join ZK60A to itself and other magnesium alloys.

MACHINING

ZK60A, like all magnesium alloy forgings, 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 the operation.

SURFACE TREATMENT

All the normal chromating, anodizing, plating, and finishing treatments are readily applicable.

Magnesium alloys have traditionally been specified by designers because of their favorable strength to weight ratios. Magnesium is approximately two thirds the density of aluminium and a quarter that of steel. Some of the more recently developed magnesium alloys have also improved resistance to corrosion and better all round mechanical properties, especially at elevated temperature.

The growing numbers of available magnesium alloys are divided into two groups: casting alloys and wrought alloys. Wrought product forms (described below) include both extruded sections and rolled sheet/plate along with tubes and forgings. Various heat treatments are used to attain maximum strength and machining of most magnesium alloys is excellent.

The specifications and alloy grades which XYMCO can be complied with are as following Table:
