thermal expansion coefficientdifferential coolingfinite element modelingThe present paper involves a metal/polymer joint in a tailcone in a kinetic energy penetrator (KEP), one of the ammunition types used by the military. It is currently made of aluminum 7075 alloy, which could be partly replaced...
The density of high-silicon aluminum alloy is between 2.4 and 2.7 g/cm³, and the thermal expansion coefficient (CTE) is between 7 and 20ppm/ºC. Increasing the silicon content can significantly reduce the density and thermal expansion coefficient of the alloy materia...
The thermal linear coefficient of expansion of aluminum is 36% greater than copper. For transmission lines, the maximum temperature is generally limited by allowable conductor sag. Excessive sagging adds weight on power lines that may lead to failure of poles and towers. Some conductors can operate...

The major reason for an increase in the room-temperature mechanical properties of the hybrid composites should be attributed to the larger hybrid ratio of SiC and B4C nanoparticles, the coefficient of thermal expansion mismatch between matrix and hybrid reinforcements and the dispersive strengthening ...
One disadvantage of aluminum is its high thermal coefficient of expansion, which reduces the material’s dimensional stability in an unstable thermal environment. Another disadvantage is the difficulty of attaining visible quality super-polished surface finishes. Aluminum alloy 6061 is a common alloy ...
LM 28Piston alloy with lower coefficient of thermal expansion than LM 13. This alloy use requires special foundry technique. LM 29Same characteristics as LM 28 but with still lower coefficient of thermal expansion than LM 28. LM 30For unlined die cast cylinder blocks with low expansion and exce...
ALUMINUM-BASE ALLOY HAVING LOW COEFFICIENT OF THERMAL EXPANSION AND HIGH STRENGTH AND ITS PRODUCTION PURPOSE: To produce an Al-base alloy having low thermal expansion characteristic, high strength, and high toughness by preparing an alloy consisting of spe... M Takeshi,増本 健,I Akihisa,... 被...
Thermal Expansion Every substance has its own coefficient of thermal expansion. The CTE of copper(18ppm/C) and aluminum (22ppm/C) is fairly close. Since aluminum PCBs excel in thermal dissipation, they do not experience significant contraction or expansion issues. They are highly durable, reliabl...
