7075 aluminium alloy is a cold treated wrought alloy that is strong and far superior to soft steel.
7075 is one of the strongest alloys commercially available. 7075 aluminium alloy has a tight structure and is highly resistant to corrosion.
Best for aerospace and marine plates. General corrosion resistance, good mechanical properties and anodic response.
Fine grain size allows for better deep drilling performance and increased tool wear resistance.
Neodymium magnets were invented in 1982 by Makoto Sagawa and others at Sumitomo Special Metals.
Its chemical formula shows that it is mainly composed of neodymium, iron and boron and other chemical elements.
Chromium-molybdenum steel is an alloy of chromium (CR), molybdenum (MO) and iron (FE), carbon (C).
It has good hardenability and can be deep hardened, instead of surface hardened as in the case of commercially available anti-saw locks.
Because of its special high-quality performance, often used in the manufacture of some high temperature, high pressure resistant valves
and pressure vessels, such as chromium-molybdenum steel safety valves, chromium-molybdenum steel gate valves, screwdriver bits, bicycles and so on.
S2 tool steel, is a kind of impact resistant tool steel. Quenching temperature 880, quenching medium brine, and
Tempering 200 degrees, hardness in HRC58-62. used in the manufacture of high-hardness hexagonal wrenches
screwdriver, batch nozzle, etc.
