IS 410 covers brass sheet and strip in various Cu-Zn compositions (63/37 to 90/10) and tempers (annealed to spring hard). 70/30 brass is most common for general engineering; 63/37 (muntz metal) for architectural work.
Specification for brass (Cu-Zn alloy) sheets, strips, and foils covering grades, tempers, dimensions, and mechanical properties.
Key Values
70/30 brass tensile (O)Min 270 MPa
70/30 brass tensile (H)Min 430 MPa
63/37 brass tensile (O)Min 320 MPa
Practical Notes
! 70/30 brass (cartridge brass) has excellent cold formability — used for deep drawing.
! 63/37 brass (muntz metal) is cheaper and used for architectural panels, condenser tubes, and hot working.
! Brass is susceptible to dezincification in certain waters — use 90/10 (CuNi) or inhibited brass for potable water.
