Metals and Alloys Machining
Metals and alloys are the most common materials used in industry, ranging from the relatively soft aluminium alloys and copper to tool steels, hardened steels and carbides that can be heat treated, as well as the very difficult to cut and most heat resistant high temperature alloys titanium, tungsten, stainless steel (SUS630，17-4ph), molybdenum, nickel and tantalum.
Material Selection Guide
Stainless steel materials
There are many kinds of stainless steel, generally austenitic stainless steel (SUS304,316) is not heat treatable, martensitic stainless steel (SUS630, 440) is heat treatable to about 55 HRC.
Copper materials
Copper that cannot be heat treated: aluminium bronze, tin bronze, silicon bronze, copper, brass, tungsten copper, red copper, oxygen-free copper. Copper that can be heat treated: beryllium copper.
Aluminium materials
There are hard aluminium and wrought aluminium, hard aluminium (7050-T7451, 7075-T651) is generally used in aerospace and other high temperature resistant environments, soft aluminium (5052, 5083, 6061) is easier to cut.
Hardened steel
Common hardened steels are plain carbon steel 1.7045, high speed steel 1.3343, alloy steel 1.5508, tool steel 1.2343 and 1.2379 (the company works with most steel companies and can buy most national steel grades)
Tungsten carbide
Extremely hard and wear resistant materials, generally machined using diamond cutting tools, the company has carbide sintering furnaces and can also purchase raw materials from well known carbide manufacturers.
Titanium machining
Titanium alloys have high thermal strength and are used at temperatures several hundred degrees higher than aluminium, and are used in aircraft engine components, skeletons, skins, fasteners and landing gear.
Heat resistant alloys
Heat-resistant alloys, also known as high-temperature alloys, are alloys with stable organization and excellent mechanical, physical and chemical properties under high-temperature use conditions.
Special alloys
Alloys such as molybdenum
tungsten
nickel
tantalum are generally used in laboratories, in the medical field, in the energy sector and in the development of new materials.

SPP Industry Ltd.
In the 1990s, SPP Industry Ltd was one of the first manufacturers to establish CNC machining in China. The company has now established five major machine parks in China, with significant achievements in the areas of 5-axis machining, precision grinding & honing, gear machining, large parts machining, custom tungsten carbide and new material development respectively.
