Aluminiumbronze – Extra hard.
AB-300 is a tough and hard aluminiumbronze with high mechanical values and high wear resistance. Â Â Â Â Â Due to the excellent sliding properties this alloy is – for example – well suited for wear and sliding parts when the opposing material is hardened steel. AB-300 is however not suited applications exposed to shock and impact stress.
Areas of use
Tool parts for plastic mould injection, sheetforming tools, guide parts , wear plates and slip rulers etc
