With features of high temperature resistance, corrosion resistance, abrasion resistance and insulation, ceramic can work in many kinds of semiconductor production equipment with condition of high temperature, vacuum or corrosive gas for a long time. Made from high-purity AlN ceramic powder, processed by cold isostatic pressing, high temperature sintering and precision finishing, it could reach the dimension tolerance to ±0.001 mm, surface finish Ra 0.1. Here is the characteristics of AlN ceramic material.Spray Granulation →ceramic powder → Forming → Blank Sintering → Rough grinding → CNC Machining → Fine Grinding → Dimension Inspection → Cleaning → PackingPlace of Origin: Hunan, China Material: AlN Ceramic HS Code: 85471000 Supply Ability: 200 pcs per month Lead time: 3-4 weeks Package: Corrugated box, foam, carton Others: Customization service available● Professional online service team, any mail or message will reply within 24 hours. ● We have a strong team provide wholehearted service to customer at any time. ● We insist on Customer is Supreme, Staff toward Happiness. ● Put the Quality as the first consideration; ● OEM & OPM, customized parts are acceptable. ● Advanced production equipment, strict quality testing and control system to make sure superior quality. ● Competitive price: we are a professional ceramic parts manufacturer in China, there is no middleman's profit, and you can get the most competitive price from us. ● Good quality: good quality can be guaranteed, it will help you keep the market share well. ● Fast delivery time: we have our own factory and professional manufacturer, which save your time to discuss with trading companies. We will try our best to meet your request.
