Information about aluminium bronze
Lagermetall AB have during year 2004, been given the possibility to offer our clients and the market, a close to complete program of extrahard aluminum-bronzes ( AB-alloys)
These AB-alloys have the following characteristica:
AB alloys - have a hardness pending from ca. 200 HB up till 400 HB. Can be used in all sorts of applications where high demands are requested for, when it comes to tensile strength, abrasion- and wear/tear-resistance as well as good sliding abilities.
Ex. on areas of use are e.g. tool-parts in injection moulding of plastics and for wear-parts within the manufacturing process of various steel alloys ( in forming-, drawing- or bending-operations for steel/stainless steel, work support blades for centreless grinding of steel bars, guide port bushings and wear strips replacing hardened steel) etc.
