It is all known that high purity alumina is difficult for metallization in mass production, however Fine-Boon company is skilled for high purity (99.0-99.9%) alumina metallization treatment in our company. Our high purity alumina metallization components still have superior brazing characteristics. No matter cylindrical or complex ceramic bodies, we have skilled solutions to guarantee consistent uniformity of bandwidth and plating thickness. Our self-produced unique formulation of Molybdenum-Manganese slurry enables us to get stronger and more robust bond strength with ceramic bodies (typical thickness: 10 to 30 碌m). After metallization, a thin metal coating (such as nickel, typically 3鈥? 碌m ) is applied to the metallization surface using either electrical or chemical plating to achieve the required wettability for subsequent brazing. This also ensures the brazing joints for metal and metalized alumina are excellent air tight for UHV field. High Purity Alumina Metallization Components Alumina Metallization Components Metalized Alumina Ceramics Shanghai Fine-Boon's strict quality control and streamlined management ensures you only receive a consistent and reliable high purity metallized alumina product with competitive price and just-in- time delivery. Both the thickness for metallization and nickel layers is always inspected using our XRF and microscopes to ensure it meets the standards or customers' specifications. Fine-boon can also provide detailed technical solutions for your requests of various metalized alumina ceramics. Fine-Boon Company is a professional manufacturer for metalized ceramic components for decades. We accumulated rich experiences and extensive knowledge and skilled engineers.

Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. The SMT4 furnace temperature tracker is used to detect the temperature distribution during the painting process to ensure the quality. The heat insulation layer is composed of a material that does not transfer heat, and the purpose is to heat insulation. The friction block is composed of a friction material adhesive, which is pressed against the brake disc or brake drum during braking to generate friction, thereby achieving the purpose of vehicle deceleration and braking. Due to friction, the friction pads will gradually wear out. Generally speaking, the lower the cost, the faster the brake pads wear. After the friction material is used, the brake pads should be replaced in time, otherwise the steel plate and the brake disc will directly contact, and eventually the braking effect will be lost and the brake disc will be damaged. The role of the braking system: deceleration, parking Basic composition of disc brakes: brake caliper, brake cylinder, brake disc, brake pads OEM8K0698451A MaterialLow metal semi metal NW1.33KG GW1.38KG Packing Size145CM*80CM*80CM Warranty30,000km a year Leading Time1-20 days Size380*19.6MM Product Operations BrandModelYearDisplacement AudiA42009>>20161.8T/2.0TChina Brake Pads website:http://www.bfaccessories.com/brake-system/brake-pads/
