Hardness evaluates a fabric's potential to resist mechanical don and abrasion. Alumina ceramics surpass steel and tungsten carbide applications in hardness. Around the Rockwell hardness scale, alumina ceramics range from HRA80-90, positioning them just below diamonds and over stainless-steel.
The exact same characteristic which makes Macor machinable means that it's rather lousy dress in resistance compared with Alumina.
What exactly is Macor product of? Macor can be a composite material crafted from fluorophlogopite (a type of Mica) in the borosilicate glass matrix (including Utilized in exam tubes and Pyrex®) in a ratio of 45/55 respectively.
Macor has a continuous use temperature of 800°C, and a peak temperature of 1000°C. Its coefficient of thermal expansion matches most metals and sealing Eyeglasses, meaning it might accomplish in severe functioning environments the place precision is a requirement.
Silicon carbide grinding wheels do the job really very well for surface grinding purposes. A water soluble coolant formulated for glass or ceramic grinding needs to be employed for all surface area grinding functions.
Macor can also be joined or sealed to by itself along with other products in quite a few ways: metallized areas can be soldered jointly and brazing has confirmed a successful approach to becoming a member of the fabric to various metals; epoxy makes a strong joint, and sealing glass generates a vacuum limited seal.
Besides Macor®, we may equipment the extremely tough ceramic substance Photoveel N®, that has an amazingly high bending strength, While using the utmost precision. We do this using our individual more info in-residence production approach and our years of expertise Together with the product or service and Within this subject.
MACOR® is often Minimize with standard higher velocity steel instruments. Carbide resources accomplish a lot better than superior pace metal and therefore are proposed for harder machining functions in addition to significant volume purposes Machining
Our portion sizing capabilities vary from micromachined sections, to parts that happen to be the size of the largest blanks of Macor® available.
Isostatic urgent is usually possibly soaked or dry bag urgent. In this method, sprayed powder is enclosed inside of a rubber or polyurethane bag and subjected to isostatic tension.
Any time you need the overall performance of a specialized ceramic- (large use temperature, electrical resistivity, zero porosity) �?and also your application needs the Prepared fabrication of a complicated shape evaluate Macor®. It's going to decrease charges and considerably decrease the time among design and style and true use.
ZERODUR® K20 is optimised to withstand better operating temperatures nearly 850°C, readily available as small, significant precision elements.
Macor® (machinable glass ceramic) features a continual use temperature of 800°C plus a peak temperature of 1000°C. Its coefficient of thermal enlargement easily matches most metals and sealing Eyeglasses.
Supports and components in many satellite borne techniques (thermally and electronically insulating)
