NEW! Optilloy™ Optimized Alloy Powder
Optilloy™ material was developed to bridge the gap in performance between the Super-MSS™ Sendust
material and the Hi-Flux material. Optilloy™ has similar DC saturation performance to Hi-Flux, yet
has core losses that are similar to Super-MSS™ Sendust. Optilloy™ will be offered in six permeabilities:
14, 26, 60, 75, 90 and 125. Contact us for more information.
Super-MSS™ utilizes an iron-silicon aluminum alloy powder which has high resistivity
and low magnetostriction. A 10,000 Gauss saturation level provides high energy storage
at a lower total loss compared with iron powder or gapped ferrites, and at lower cost than
Molybdenum Permalloy Powder (MPP) cores provide the maximum Q and lowest core
losses of all commonly available powder core toroids. MPP is the most stable core with
respect to temperature and AC Flux. It has the widest range of permeabilities and is
considered the premium material for direct current output inductors of Switched Mode
HI-FLUX™ (HF) cores are a 50% Nickel – 50% Iron distributed gapped powder
core. HF has up to 15,000 Gauss saturation flux density and core losses significantly lower
than iron powder cores.
When used in applications with high DC current, HF cores can
provide a reduction in inductor size as well as total cost.
The 6.5 wt% Iron-Silicon material offers significant advantages, displaying excellent soft
magnetic properties such as high saturation magnetization, near zero magnetostriction
and higher resistivity.
An Iron/Silicon powder core has a typical 15,000 Gauss saturation flux density
and core losses significantly lower than iron powder cores at high frequencies.
In addition to ring cores, a selection of standard size E cores and Block cores is available along
with the ability to produce custom dimensions and other geometries.

MAPC Company Overview
The Arnold Powder Core Division was acquired from Arnold Magnetics Technologies by
Micrometals Incorporated of Anaheim, California in January of 2010. Arnold's extensive
range of MPP (molypermalloy powder), SUPER-MSS™ (sendust), HI-FLUX™
(50/50 nickel iron), Iron/Silicon and
other alloy based powder cores
are manufactured in large quantities with competitive pricing and outstanding quality in Arnold's Shenzhen,
China factory. MAPC can supply a wide range of standard
toroid O.D. sizes, from 0.14 inch (3.6 mm) to 5.218 inch (133 mm), and is also capable
of providing non-standard, customer specified physical dimensions.
