Product Specifications/Summary
MA-INV36 (low-expansion material) | Has only one tenth of the thermal expansion of iron and general alloys. |
---|---|
MA-S-INVER (low-expansion material) | At a value near zero, it has the least thermal expansion of any metal material. |
MA-F15KV (sealing material/constant modulus material) | Long known as alloy for sealing hard glasses. Since its thermal expansion is similar to hard glasses and ceramics, this material has excellent settlement ability and workability. |
MA902 (sealing material/constant modulus material) | Known as alloy with a very small thermal coefficient of Young's modulus. Its coefficient of thermal expansion is also small. It can achieve high strength by selecting the appropriate heat treatment conditions. |
MA-B2 (high-strength, oxidation-resistant, and low-expansion material) | This is originally a corrosion-resistant material that has corrosion resistance against hydrochloric acid of any density at the boiling point at a maximum. It is is also used as a material for electronic componants. Since it is non-magnetic, it is suitable for parts that are averse to magnetic fields. |
SUS304 (comparison material) | Mainly used as a corrosion-resistant material in the petrochemical industry, etc. and also commonly used for low- and high-temperature industrial applications and consumer durables. |
MA-S-INVER : Commonly called super invar
MA-F15KV : Commonly called kovar
MA902 : Commonly called NI-SPAN-C
