SILICON NITRIDE CUSTOM COMPONENTS IN LARGE QUANTITIES

Ceramco adds silicon nitride (Si3N4) to its list of production formulations for additive manufacturing (LCM) and high pressure injection molding (HPIM)

Ceramco, Inc., building upon its expertise in the near-net shaping of alumina and zirconia components, is now also near-net shaping silicon nitride. Tool-free LCM and HPIM makes these non-oxide silicon nitride components achievable and more cost effective. Ceramco’s near-net shaping of silicon nitride in many cases eliminates the need for any follow-up machining.

Ceramco’s silicon nitride shares the same desirable characteristics of high strength and toughness of their zirconia, but at about half the weight. The material performs in application temperatures up to 1200° C and has high resistance to wear and corrosion. Silicon nitride stands alone in its ability to withstand mechanical impact and exhibits high mechanical strength when exposed to sudden stresses.

Silicon nitride components manufactured by Ceramco include: cutting tools, sensor shields, high velocity, defense-related articles and other tough service applications. Ceramco anticipates adding LPIM (low pressure injection molding) of silicon nitride to its capabilities in the near future.

new A998 alumina flat washer sizes now in stock

New, Larger Sizes of Ceramic Flat Washers Now Part of Ceramco’s Stock Ceramic Fastener Inventory

Flat washers made of Ceramco’s A998 alumina in seven larger U.S. inch sizes and five larger Metric sizes are now in-stock and available for immediate shipment.

In answer to an ever-increasing demand for stock ceramic fasteners in a greater variety of sizes, the new A998 alumina U.S. inch flat washer sizes include: 7/16″, 1/2″, 9/16″, 5/8″, 3/4″, 7/8″ and 1″. The new Metric sizes of Ceramco’s A998 alumina flat washers include: M10, M12, M14, M16 and M20. Other new sizes are planned.

Ceramco’s stock ceramic fastener inventory, including these new larger flat washers, are 100% molded, using our near-net shaping process and then fired to full density. Ceramco stock ceramic fasteners are never machined or fatigued from harsh grinding.

Ceramco’s stock ceramic washers, bolts and hex nuts are heat resistant, corrosion resistant, non-conductive and do not out-gas. Markets served by Ceramco’s stock ceramic fasteners include: aviation and aerospace, scientific instrumentation, energy, personal care and textile manufacturing.

Ceramco’s stock ceramic washers and their matching bolts and nuts are ideal in almost any application in which metal alloy fasteners or plastic fasteners fail, or simply do not possess the properties demanded by the environments in which they must perform.
All of Ceramco’s stock ceramic fasteners are made in America, in Center Conway NH.
