Beryllium Copper
แปลว่า(english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc.
rapid-hardening cement
แปลว่าปูนซีเมนต์แข็งตัวเร็ว
Brinell Hardness Test
แปลว่า(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.
harden surface
แปลว่าพื้นหน้าดินแข็ง, พื้นที่อันแน่นและแข็ง
Retardation
แปลว่า(Concrete Engineering) Delaying the hardening or strength gain of fresh concrete, mortar or grout.
Accordion Reed Steel
แปลว่า(english) Hardened, tempered, polished and blued or yellow flat steel with dressed edges. Carbon content about 1.00. Material has to possess good flatness, uniform hardness and high elasticity.
Boron Steels
แปลว่า(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.
