LM’s comparison list between different
norms from Copper alloys
Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand
column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor
differences. The column in the middle states the norm and its country of origin.
With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.
3.模具使用壽命長:預算模具的成本和生產(chǎn)的連續(xù)性,對于生產(chǎn)廠家來說模具預期的使用壽命是非常重要的,在鈹銅的強度和硬度符合要求的情況下,鈹銅對模具溫度應力的不敏感性可以大大的提高模具的使用壽命,在確定使用鈹銅模具材料前也要考慮到鈹銅的屈服強度,彈性模量,熱導率和溫度的膨脹系數(shù)。鈹銅對熱應力的抵抗性遠比模具鋼要強的多,從這一點來說鈹銅的使用壽命是令人注目的!
4.熱穿透率高:除拉導溫性能,模具材料的熱穿透率對塑料制品的影響也相當重要,在使用鈹青銅的模具上,可以消除過熱痕跡,如果熱穿透率低,模具壁遠端區(qū)域的接觸溫度就會越高,這樣會使模具的溫差加大,在極端的情況下會引起區(qū)域溫度的變化從塑料制品的一端的縮痕延伸到另一端的過熱的產(chǎn)品痕跡。
