PRECISION ALLOYS
Elastic Alloys
Elastic alloys boast an impressive range, including high elastic and constant elastic variations. These alloys are pivotal in crafting elastic elements such as the intricately designed elastic sensitive components, energy-efficient storage elements, and precise frequency elements, indispensable in the realm of precision instruments.
Expansion Alloys
A diverse category known as expansion alloys, these include Kovar alloys, ceramic sealing alloys, low expansion alloys, and the remarkable constant expansion alloys.
These versatile alloys find extensive application across the electronic industry, precision measuring tools, sophisticated precision instruments, and the demanding fields of low temperature engineering, among others.
Soft Magnetic Alloys
Soft magnetic alloys stand out with their exceptional characteristics of high permeability and minimal coercivity within weak magnetic fields. Sorting these alloys involves an array of compositions based on their elemental makeup.
They encompass electromagnetic pure iron (industrial pure iron), iron-silicon alloy, iron-nickel alloy, iron-aluminum alloy, iron-silicon-aluminum alloy, and the distinguished iron-cobalt alloy, each offering unique properties.
Diverse Product Forms
Available in an extensive range of forms: pipe, plate, strip, round rods, flat rods, forgings, wire, special profiles, and expertly crafted extrusions.
