Precision Alloy 4J33 4J34 4J42 4J43 4J44 4J47 4J47 Fe Ni Co Alloy Strip & Coil& Foil With Nice Price
Precision alloy, is a metal material with special physical properties (such as magnetic, electrical, thermal and other properties).Most precision alloys are based on ferrous metals, while a few are based on nonferrous metals.It usually includes magnetic alloys (see magnetic materials), elastic alloys, expansion alloys, thermobimetallic, electrical alloys, hydrogen storage alloys (see hydrogen storage materials), shape memory alloys, magnetostrictive alloys (see magnetostrictive materials), and so on.
| Grade | 4j29,4j36,4j42,4j43,4j44,4j47,4j50etc |
| Sharp | wire, bar/rod, strip, sheet, tube |
| Standard | GB/T15018,YB/T5231-2005,YB/T5241-2005,YB/T5235-2005etc. |
| Basic performance | It is divided into low-expansion alloy and fixed-expansion alloy, the latter is also known as sealing alloy.Expansion alloy besides has the specific thermal expansion coefficient, according to the different USES also requires a good sealing property, weldability and corrosion resistance, machinability and cutting, and in the use of expansion characteristics caused by the temperature range there is no obvious change of phase transformation, its product is commonly bar, sheet, strip, wire and tube and so on. |
| Expansion alloy applications | It is widely used in glass, metal and ceramic sealing in avionics and instruments, electric vacuum industry and other electronic devices, electric light source and other fields. |
