Young's modulus, the Young modulus, or the modulus of elasticity in tension or compression (i.e., negative tension), is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise. The analysis is, of course, not significantly different from analysis given for single exposure technique and the resulting interference pattern is determined by the phase difference between the . Copper is tough and ductile, but is valuable due its ability to conduct electricity. Standard beryllium copper alloys contain close to 2% beryllium, while the beryllium content in proprietary alloys can range from 1.5% to 2.7%. Thermal Conductivity Btu/ sq ft/ ft hr/ F at 68F. While best known for their historical value they are used for self lubricating bearings, pumps, valves, electrical contacts and springs, etc. Publist#: 144/8. I am running a simulation of a simple brazed copper assembly; brazed at 1050C. 109.
