the physical properties of stainless steel square hole mesh/stainless steel screen mesh;
the density, the quality of unit volume of metal is called density, density according to size, can be divided into light metals and heavy metal to metal.
For example, aluminum, magnesium, titanium and its alloys are light, copper, lead, tin and its alloy belong to heavy metal.
在金属中,最轻的是镁,最重的是铂,金属和合金的密度,在工业上是很重要的,两种强度极限相同的金属材料,则密度小的材料就可以制造出又轻又好的机器
熔点,金属与合金从固体状态向液体状态下转变时的熔化温度称为熔点,在工业上常用的纯金属中,锡的熔点较低,钨的熔点最高,根据金属材料熔点的高低,在工业上可以有不同的用途,例如用低熔点的铜可以制作熔断器的保险丝,用高熔点的钨可以制作电灯泡内的灯丝
导电丝,金属传导电流的性能称为导电性,金属具有良好的导电性,其中银最好,铜铝次之,因为银是贵重金属,所以银在工业上仅用于电气接触头上,耐用铜铝制作导线,工业上有些地方还需要用一些导电性能差的高电阻合金,例如康铜,锰铜,及铁铬铝合金等,这些材料用于制造元件和电炉 的加热元件
热膨胀性金属加热时体积增大的性质叫做热膨胀性,各种金属与合金具有不同的热膨胀性,用膨胀系数来表示,物体 温度升高摄氏度所增加的长度与原有长度的比,叫做膨胀系数,常用的测量工具,千分尺,块规行装,要求用线膨胀系数小的金属材料制造以减少误差
导热性,金属能够传导热量的性能称为导热性,这是金属与合金的得要性质,金属在加热或冷过程中,由于内外温度不同,因而具有不同的膨胀和收缩,使金属内部产生应力,当内应力大于金属的强度极限时,金属便发生破熬裂,金属的导热性越差,在加热或冷却的其内外温度差别就越大,也就是越容易因急剧的或冷却而破裂
磁性,金属材料有磁场中受到磁化程度的影响称为磁性,耐具有磁性的物质叫做铁磁体,金属中的铁镍钴及其合金,是具有显著磁性的铁磁体
