70/30 cartridge brass
A high-copper brass family often selected for deep drawing and formed components when the specified grade permits.
Review specification details →Brass flat products for industry
Source brass sheets and strips by alloy, temper, thickness, dimensions, finish and quantity for forming, fabrication, hardware and engineering requirements.
Product overview
S.K. Metal supplies brass sheets and strips for buyers who need material matched to a defined copper-zinc composition, grade, temper, gauge and finish.
Brass offers a useful combination of formability, corrosion resistance, appearance and machinability, but properties change with composition and temper. Buyers should specify whether the material will be deep drawn, stamped, bent, machined, polished, plated or used for electrical, decorative or engineering components.

Grades and formats
Start with the forming method and final application, then confirm composition, grade, temper and dimensions.

Review specification details →General-purpose copper-zinc sheet material available subject to the required grade, temper and dimensions.
Request grade availability →Brass sheet and strip considered for compatible pressed, formed and engineering components.
Send your specification →Narrow-width flat material for terminals, hardware, decorative trim and repeat component production.
Request strip availability →Surface-finished sheet for compatible architectural, decorative and visible fabricated components.
Discuss finish requirements →Perforated material for screens, panels and decorative applications when hole pattern and open area are specified.

A complete specification helps avoid purchasing an unsuitable composition, grade, temper, thickness or finish.
Important: Brass composition, temper and dimensions materially affect forming behaviour and performance. Confirm the exact grade, test documents, dimensions and permissible tolerances in the approved quotation.
Applications
The correct brass grade, temper and finish depend on the forming process, component design and service environment.
Formed or machined components such as plates, escutcheons, brackets and compatible hardware.
Terminals, contacts and conductive components made from the brass grade specified by the design.
Panels, trim, signage and architectural details where surface appearance and finish are important.
Compatible formed and heat-transfer parts produced from brass material selected for the application.
Cups, shells and formed components manufactured from a suitable deep-drawing brass and temper.
Fabricated covers, shims, plates, gears and other components produced to an approved material specification.
Quality and documentation
Ask for documentation applicable to the exact brass grade, temper and producing source being quoted. Buyers can also review the Copper Development Association alloy data when evaluating cartridge-brass specifications.
Discuss your material requirement →Ordering checklist
Send a complete material schedule when several brass grades, gauges, sheet sizes or strip widths are required.
State whether you require sheet, strip, coil or perforated brass material.
Provide the complete brass designation, nominal composition, temper and applicable material standard.
List thickness, width, sheet length, coil dimensions, tolerances and preferred unit of measure.
State polish, brushing, plating, protective film, edge condition and intended fabrication process.
Include weight or sheet count, packing, delivery location, schedule and documentation requirements.
Frequently asked questions
Provide product form, brass grade, temper, thickness, width, length or coil dimensions, finish, tolerances, quantity, delivery location and documentation requirements.
It is a wrought copper-zinc alloy family commonly associated with approximately 70% copper and 30% zinc. Specify the exact grade, such as the applicable UNS or project designation, rather than composition alone.
Temper affects hardness, strength, ductility and forming performance. The same brass grade behaves differently in annealed and cold-worked conditions.
Slitting availability depends on starting material, thickness, required width, edge tolerance, quantity and processing capability. Include these details with the enquiry.
Document availability depends on the product, producing source and order. State the exact certificate or inspection requirement before quotation.
Finish availability depends on grade, sheet size, surface condition and quantity. Provide a finish reference or approved sample where appearance is critical.
