12007-27-1 Usage
Industrial uses
Molybdenum boride, Mo2B, has a specificgravity of 9.3, a Knoop hardness of 1660, anda melting point of about 1660°C. Tungstenboride, W2B, has a specific gravity of 16.7 anda melting point of' 2770°C. Titanium boride,TiB2, is light in weight with a specific gravityof 4.5. It has a melting point at about 2593°C.Molded parts made from the powder have aKnoop hardness of 3300 and a flexural strengthof 241 MPa, and they are resistant to oxidationto 982°C with a very low oxidation rate abovethat point to about 1371°C. They are inert tomolten aluminum. Intermetal powders of beryllium–tantalum, beryllium–zirconium, andberyllium–columbium are also marketed, andthey are lightweight and have high strength.Sintered parts resist oxidation to 1649°C.
Check Digit Verification of cas no
The CAS Registry Mumber 12007-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12007-27:
(7*1)+(6*2)+(5*0)+(4*0)+(3*7)+(2*2)+(1*7)=51
51 % 10 = 1
So 12007-27-1 is a valid CAS Registry Number.
