Applications that require a material that is non-conductive as well as rust, heat, and wear resistant rely on the strength and durability of ceramics. Having the ability to be shaped and formed to fit any application, ceramics are an ideal choice for insulating and securing fittings.
An advancement in ceramic technology is the development of the ceramic washer, which is the ideal choice for insulating a connection and providing a tight seamless union between surfaces. Unlike traditional washers, once an alumina ceramic washer is installed, it remains tightly locked in place and does not wear or suffer any form of atmospheric damage.
What is an Alumina Ceramic Washer?
A ceramic washer has the same shape and configuration of all washers and can be produced with flanged, grooved, plain, slotted, or tube eyelets. Since ceramic material can be shaped and formed to any size or dimensions, alumina ceramic washers are the first choice for harsh, stressful, and hazardous conditions.
Basic ceramic material is made from natural elements that have been hardened by a heat treatment to remove contaminants and strengthen the chemical bonds of the ceramic. It is this process that produces the exceptionally durable material that is so vital to industrial and manufacturing processes.
Washers made from alumina ceramic have the same properties that have made ceramic such an important part of product and component production. The introduction of ceramic washers is the next step in the implementation of ceramic as a factor in construction and assembly operations.
Why Ceramic Washers?
All washers serve the same function, a thin plate with a hole that distributes and spreads the load of a threaded fastener such as a bolt, screw, or nut. They are also used as spacers, pads, locking devices, and a means for suppressing vibrations.
The traditional view of a washer is a flat metal disk with a hole in the middle that is placed around a bolt or screw as it is inserted, connected, and tightened. Though this is a common interpretation, metal washers wear, rust, and deteriorate over time, which necessitates replacing them. In critical applications, the replacement process can be tedious if the washer has been in place for several years.
All of the negative features of metal washers are eliminated with ceramic washers, which are made from natural materials that do not suffer the effects of aging. Every form and shape of washer found in metal washers can be produced in alumina washers. The distinguishing features are its excellent, exceptional, and undeniable durability.
Types of Ceramic Materials Used for Ceramic Washers
As with metals, there is more than one type of ceramic used to make ceramic washers. All of the various forms can be shaped, formed, and manufactured to fit the needs of a specific application. The two most common types are Alumina Oxide (Al2O3) and Zirconia oxide (ZrO2).
Between alumina oxide and zirconia oxide, alumina oxide is the most widely used. Ceramic washers made from alumina oxide are ideal for electrical insultation due to their mechanical strength as well as their wear and chemical resistance.
An advantage of zirconia oxide is its fine grain smooth surface that can form a tight and secure seal for surface connections. It has exceptional strength and toughness with a high-quality appearance. Zirconia oxide ceramic washers have a usable temperature range of 3812o F or 2100o C with a melting point of 4900o F or 2700o C, which is the reason that it is so thermal resistant.
Regardless of the ceramic material, ceramic washers are available as flat, lock, vented, and Belleville washers to name a few. Whatever configuration of washer that can be made from metal can be manufactured as a ceramic washer.
