HTB-3 : MANGANESE BRONZE / HIGH TENSILE BRASS

Description :

Manganese Bronze comes from a family of High Strength Copper based alloys which include Manganese as the principal alloying element. These alloys generally have higher amount of zinc because of which they are also referred as High Tensile Brass and relatively smaller additions of Iron, Aluminium and Lead. Manganese Bronzes are most commonly used in applications which requires corrosion resistance, anti-seizing properties, coupled with higher strength.

HTB3 is among the hardest of the copper alloys which is used for wear resistance at slow rubbing speeds. It has higher mechanical properties as compared to HTB1 but is not recommended for marine use. HTB3 produces fine swarm while machining but with increased tool wear.

AEPL produces C-66800, C-67000, C-67300, C-67400, C-67500, C-67600, C-86200, C-86300, C-86500, C-86550, CW-718R, CW-723R, HBSC-1, HBSC-2, HBSC-3, HBSC-4, HTB-1, HTB-2, Manganese Bronze/ High Tensile Brass alloy in the form of Certified Ingots weighing from 8 to 10 Kgs each.

QUALITY :

AEPL has implemented a quality system for Copper Based Alloys where all processes are monitored from start to finish i.e. from procurement of raw material, their combination, manufacturing processes, measurement and chemical analysis. We maintain our own laboratory with calibrated equipments to ensure delivery of certified ingots as per International Standards and satisfy clients' requirements. The equipment includes Optical Emission Spectrometer which uses arc and spark excitation technology. Samples of test reports are available upon request.

VALUE ADDED SERVICES :

AEPL manufactures and supplies Copper Alloys products to Domestic as well as International Markets. Located at a single site, our smaller foundries are equipped to use in-house certified ingots and create complex shapes of Copper alloy castings and turn them into finished components using Drilling, Grinding and CNC turning centres.
