Product Detail1

Shanghai Metal Corporation is a leading bronze sheet/plate manufacturer and supplier.

Bronze sheet/plate is a flat-rolled copper alloy product with tin as the primary alloying element. It is widely applied in marine engineering, chemical processing, electrical manufacturing, and architectural decoration. This material effectively solves problems of seawater corrosion, mechanical wear, and electrical conductivity. For example, it is used to fabricate ship propellers, valve parts, bearing bushes, and electrical spring contacts. With high fatigue resistance and thermal conductivity, bronze plates extend the service life of equipment operating in harsh environments.

1. Material Composition: Copper (Cu) base metal with Tin (Sn) as primary alloying element. Trace elements (P, Al, Mn, Si) can be added on request.

2. Product Structure: Solid flat sheet/plate, uniform thickness (0.1–50 mm), dense single-phase or dual-phase metallic microstructure.

3. Role of Components: Copper matrix provides electrical and thermal conductivity; dissolved tin and trace elements enhance strength, hardness, wear, and seawater corrosion resistance.

4. Structural Differences: By alloy — Phosphor Bronze (high elasticity), Aluminum Bronze (high corrosion/high strength), Silicon Bronze (good weldability); by temper — Soft (O), Half-Hard (H02), Hard (H04).

5. Application Scenarios: Phosphor bronze for spring contacts and wear bearings; aluminum bronze for propellers and desalination pipes; silicon bronze for chemical containers and corrosion-resistant structures.

1. Superior Corrosion Resistance: Resists seawater, acids, and industrial chemicals, extending equipment life and cutting maintenance costs.

2. High Wear Resistance: Tin-rich matrix with low friction and high surface hardness minimizes wear under high load and friction, ensuring reliability.

3. Excellent Electrical & Thermal Conductivity: Efficient heat dissipation and stable current transfer improve energy efficiency and prevent overheating.

4. Good Machinability & Formability: Easily cut, punched, welded, and cold-worked without cracking, accelerating production and cutting costs.

5. High Fatigue Strength: Resists cracking and fatigue under cyclic loading and vibration, ensuring integrity in springs, bushings, and bearings.

6. Non-Sparking & Non-Magnetic: Non-magnetic, no sparks on impact or friction, enhancing safety in hazardous areas and compatibility with sensitive electronics..

1. Marine Engineering: Ship propellers and seawater pump bodies; aluminum bronze (10–50 mm) resists corrosion and cavitation.

2. Electrical & Electronics: Relay contacts and connectors; phosphor bronze (0.1–2 mm, hard) offers elasticity and conductivity.

3. Heavy Machinery: Bearing bushes and worm gears; tin bronze (5–20 mm) provides low friction and high load capacity.

4. Chemical Processing: Reactor liners and acid-resistant flanges; silicon bronze (3–15 mm) resists chemicals with good weldability.

Standard Packaging:

Each Brass sheet is first packed into Craft paper; then loaded into an export wooden box or wooden plate for international shipment.

Shipping:

We support FCL and LCL sea freight, air freight, and express delivery, depending on order quantity and destination. Available trade terms include EXW, FOB, CIF, and others upon request. Shipping costs are calculated based on cargo volume, gross weight, destination, and selected transportation method.

Lead Time：

Sample: 10 working days

Standard orders:15~25working days

Custom orders :35 ~40 working days

Q1: What is the MOQ and production lead time?

A: MOQ depends on grade, temper and dimension; please contact our sales team to confirm for your size. Samples take 3–7 working days, standard orders 15–25 working days, and customized orders 25–40 working days from order confirmation.

Q2: How long does sample preparation take?

A: Samples are normally ready within 3–7 working days. Standard grades (C2600, C2680, C2801) in common tempers and sizes can be cut from stock; custom tempers or surface finishes may take longer.

Q3: What information do you need for a custom quotation?

A: Please provide grade, thickness, width, length, temper, quantity, surface finish and destination port. If the material will be deep drawn, stamped or CNC machined, mention the process so we can recommend the right temper. A quotation is normally issued within 1–2 working days after we receive the requirements.

Q4: What quality standards and certifications do you provide?

A: We supply to JIS H3100 and ASTM B36, and each batch can be delivered with a mill test certificate (MTC) covering chemical composition and mechanical properties. In-house tests include spectrum analysis, grain size, hardness, tensile strength and elongation; third-party inspection (e.g. SGS) is available on request.

Q5: What is the difference between C2600, C2680 and C2801?

A: The copper content differs: C2600 contains 68.5–71.5% Cu, C2680 64.0–68.0% Cu and C2801 59.0–62.0% Cu. Higher copper gives better ductility, formability and corrosion resistance, so C2600 suits deep drawing and terminals; higher zinc raises strength and machinability and lowers cost, so C2801 suits fasteners and machined parts; C2680 is the balanced middle choice for general stamping and hardware.

Q6: How do I choose the right temper for my parts?

A: Use soft (O) for deep drawing, bending and coining; 1/4H–1/2H for parts that need some forming plus flatness; H for flat stamped parts and springs where strength matters; EH–SH for elastic or spring components. If the part will be formed after stamping, choose a softer temper to avoid cracking.

Q7: Can you cut brass sheet to custom sizes and supply narrow widths?

A: Yes. We shear plates to custom length and slit coils into narrow strips; custom width starts from 10mm. Please give the finished dimensions and required tolerances, and we will confirm the cutting plan and delivery lead time.
