SAEC XC-10 MC Cartridge

Its main features include a cantilever made of a composite structural material of solid boron rod and aluminum alloy, a Super Sendust coil winding frame, a Super Line Contact stylus, a body machined from a special light alloy with a mirror finish on the surface, and a base made of a mirror-finished high-rigidity alloy composite material.

Sendust is a magnetic metal powder that was invented by Hakaru Masumoto at Tohoku Imperial University in Sendai, Japan, circa 1936, as an alternative to permalloy in inductor applications for telephone networks. Sendust composition is typically 85% iron, 9% silicon, and 6% aluminum. The powder is sintered into cores to manufacture inductors. Sendust cores have high magnetic permeability (up to 140 000), low loss, low coercivity (5 A/m) good temperature stability, and saturation flux density up to 1 T.
Due to its chemical composition and crystallographic structure, Sendust exhibits simultaneously zero magnetostriction and zero magnetocrystalline anisotropy constant K1.
Sendust is harder than permalloy and is thus useful in abrasive wear applications such as magnetic recording heads.
