1. Lead, Lead, Lead, Plumbum (Pb) Lead is very very soft, soft but resilient, has a bright white color that is very clearly visible in the fracture or splinter. Lead has a density (ρ), which is as high as = 11.3 kg/dm3 with a melting point of 3270C, is used as an anti-radiation Nuclear insulator. Lead is obtained from Plumbum-Sulphur ...

4. Tin, Tin, Stannum (Sn) Tin, Tin, Stannum (Sn) is a shiny white metal, very soft with a low melting point that is 2320C. This metal has high corrosion resistance properties so bnayak used as a coating material on a steel plate, used as packaging in a variety of food products because Tin is highly resistant to fruit acids and ...

32. Hafnium (Hf) Hafnium (Hf) have the same properties as the zirconium and include heavy metals, has a tensile strength of 340 N/mm2, 180 HV hardness number and melting point of 21300C. Hafnium (Hf) can be formed with the engine at low rpm. Splicing Hafnium be very suitable to provide high current, Hafnium is used as materials for a pressure ...

9. Copper, Copper, Cuprum (Cu) Copper is one of the important metal as the material use is very widespread technique used both in the pure state or in the form of alloys. Pull the copper with the power of 150 N/mm2 as Copper Cast and the cold working process Copper tensile strength can be increased up to 390 N/mm2 as ...
