C
Carbon
is a chemical element. In nature it either appears chemically bound (such as hydrocarbon) or in pure form (such as diamond).
CE-mark
Many European directives specify that products must bear a CE mark. The manufacturer thus declares the product's compliance with all current European regulations and that it has undergone the specified conformity assessment process. It should be noted that unlike the GS symbol, for example, the CE mark does NOT necessarily have to be awarded by an independent testing and certification body.
Compression set
The is a measure of how elastomers behave in long-running pressure deformation and subsequent relaxation. The permanent deformation is an important parameter for seals of . A of 0% means that the body has fully achieved its original form, a of 100% expresses that the body was completely deformed.
Copper
is a chemical element. It is a relatively lightweight metal that is well workable. is an excellent heat and power conductor.
Copper-beryllium
-beryllium is a alloy containing 0.4 to 2% beryllium. -beryllium alloys provide very good mechanical and electrical properties. The strength they achieve after curing is the highest of all alloys and the curing process also achieves high electrical conductivity. Furthermore, CuBe is extraordinarily elastic.
Corrosion
describes the reaction of a material with its environment wherein the material undergoes noticeable change. This change may adversely affect the function of the system or component. Rusting is the most common type of . This is where metal oxidises
