Alumina sees application from aerospace to medical, from bearings to analytical instrumentation, from electrical standoffs to semiconductor processing. In addition, these materials lend themselves well to be hermetically sealed to metals through metallizing and brazing methods.

STC supports the goals of REACH, which are consistent with our own commitment to promote the responsible manufacturing, use, and handling of chemicals. After a complete bi-annual review of the materials used in our parts and the manufacturing process, we can advise you, our customers, that STC is Reach compliant to the 240 substances now on the ECHA list.

STC Material Solutions is committed to ensuring that its products and product components are responsibly manufactured. Vendors are expected to ensure that products supplied to STC Material Solutions do not contain metals derived from “conflict minerals” – tin, tantalum, tungsten and gold, or their derivatives – that directly or indirectly finance or benefit armed groups in the Democratic Republic of the Congo (or any adjoining country). To promote compliance with this standard, Vendors are expected to:

Aluminum Oxide, or alumina, is the most common technical ceramic material used today. The versatility of alumina stems from its broadly impressive material properties, ease of manufacture, wide availability, and budget-friendly cost. STC produces a range of alumina purity from 74% alumina to 99.96% alumina – these bodies are the industry work-horse materials for applications that require electrical isolation, wear resistance, high temperature resistance, and good mechanical strength.

RoHS 3 (EU Directive 2015/863) adds Category 11 (catch-all) products and adds four new restricted substances – all phthalates. The four phthalates are mainly used as insulation plasticizers and are on the REACH list of SVHC (Substances of Very High Concern). The expanded list for RoHS 3 is thus as follows:

Our High purity aluminas make for improved corrosion resistance due to lower impurity/silica content. Higher hardness, increased dielectric strength, and in some cases, superior flexural strength. Finer grain sizes also allow for smooth surface finishes. The grade of alumina is selected to best fit the application.
