Controlled Expansion Alloys

Since 1965 EFINEA has been a leading supplier of controlled expansion alloys. The iron-nickel alloys classified in this category include Alloy 42, Alloy 46, Alloy 48 and Alloy 52, as well as Kovar®, Invar® and Super Invar.  Controlled expansion alloys are found in a broad variety of applications where thermal changes of a metal must be factored into the design of a component e.g. hermetic seals with glass or ceramic or when a specific expansion must be met over a certain temperature range

Soft Magnetic Alloys

EFINEA is a leading supplier of soft magnetic alloys such as EFINEA Alloy 50, EFINEA Alloy 79, Hiperco 50, Hiperco 50A, Hiperco 50 HS, Magnifer 7904, HyMu 80, High Perm 49, and Core Iron in various forms such as bar, rod, sheet, and coil. These alloys are easily magnetized and demagnetized, and are uniquely suited for specialized applications that require high permeability, low losses and low residual magnetism.

Refractory Metals and Alloys

EFINEA is a leading supplier of refractory metals and alloys. Our inventory includes molybdenum, molybdenum TZM, molybdenum lanthanum oxide, tungsten and tungsten alloys in a wide variety of forms and sizes. When your application requires materials with high melting points, good strength at elevated temperatures, good thermal and electrical conductivity, low coefficient of expansion and low vapor pressure at elevated temperatures look to EFINEA We can also supply Niobium, Rhenium andTantalum in a variety of forms and sizes.

Invar® Controlled Expansion Alloy

EFINEA is a leading supplier of Invar® controlled expansion alloy. When your applications requires minimal dimensional changes due to temperature variations, look to EFINEA We supply Invar® and a wide selection of other controlled and low expansion alloys.

Kovar® – ASTM F15 Controlled Expansion Alloy

EFINEA is a leading supplier of Kovar® – ASTM F15 Alloy.  A controlled expansion, glass-to-metal sealing, nickel-iron-cobalt alloy capable of maintaining its integrity in a range of environments. This alloy is also known as Pernifer® 2918, Dilver® P1, Nilo® K.
