All alumina bodies possess very good mechanical properties such as hardness and compressive strength. They also hold up well under harsh conditions such as acid corrosion, high wear areas, and sliding abrasion. They also possess very good electrical insulation properties and have very specific thermal conductive and thermal expansion rates.
92% Al203; Has very good electrical and mechanical properties and is metallized easily. The black body is used primarily for lids and when metallized and plated with gold has a very distinct appearance.
94% Al203; Possess very good electric and mechanical properties and is very easily metallized with the MoMn process.
96% Al203; This is our standard body and it has been formulized to meet with good success with just about anyone’s MoMn process. This body still possesses the same good mechanical and electric properties as the previous two alumina bodies.
99% Al203; This body is used extensively in the medical industry. Its finer grain allows it to be polished to achieve fine micron finishes making it the material of choice for pump manufacturers and it is used for wire/thread guides as well as for mechanical seals. Though it can be metallized it normally does not lend itself to that process due to its lack of glassy phase.
Here at ACCI almost everything we manufacture is to the customer’s specifications. Lead times for custom parts vary from part to part. Typically an as pressed part that requires new tooling will have a delivery time around 8-10 weeks. If the part can be green machined you will be looking at a delivery time around 3-6 weeks. The best way to determine if we can make the part you require and the lead time is to contact us for a quote.
Below is a list of standard parts that we offer. Standard parts are usually in stock and can be shipped once the purchase order is received. If a part is not in stock typical delivery is 3-4 weeks, if not sooner.
