机械性能是铜合金质量的重要依据之一.检验每炉次熔铸的铜合金铸件的机械性能是用同炉次所浇试棒进行试验的.但是不同形状的试棒对于某一牌号铜合金来说,将会得出不同的机械性能.因为试棒的机械性能与它的合金成分、铸造特性、浇铸温度、浇铸方法以及在浇铸后的冷却速度有很大关系.如果选择不当,就会得出低的机械性能,因而使本来不应该报废的铸件报
Mechanical properties of copper alloy is one of the important basis for testing the mechanical properties of cast copper alloy castings per furnace is tested with the same level of cast rods, but different shapes of test sticks for a certain grade of copper alloy to Said that different mechanical properties will be derived because the mechanical properties of the test rod are strongly related to its alloy composition, casting properties, casting temperature, casting method and cooling rate after casting. If not chosen properly, Out of low mechanical properties, so that should not be scrapped casting reported
