Jay Jalaram Extrusions

We are manufacturer of brass rods and brass bars with wide range of alloy grades and profiled shapes like round, bar , hex and other customized shapes.

Our brass extrusion rods size ranges form 4mm diameter to 100mm as per required material grade.

All our products are compulsorily passed through spectrometer testing for alloy composition testing and hence we guarantee the material grade composition.

Free Cutting Brass Rods

Use: Free Cutting Brass Rod is also known as free machining brass or leaded brass and is mainly used for high speed machining like fasteners, gears, architectural extrusions, automotive engineering parts, etc. as it is corrosion resistance and has excellent machine ability.
