What are the common uses of brass plates in industry and decoration?

Common Uses of Brass Plates

1. Mechanical Load-Bearing Components

Made of high-strength brass, it can withstand significant tensile and impact forces, and is commonly used in critical load-bearing components such as heavy-duty bearings, precision gears, and structural bushings.

Its excellent wear resistance and hardness ensure long-term reliability in high-load operating environments.

2. Engineering and Construction Machinery

Widely used in guide plates, slides, and liners of mining equipment and construction machinery, it can withstand harsh conditions such as dust, moisture, and frequent friction.

Suitable for hydraulic systems, track roller bushings, and other parts requiring high strength and corrosion resistance.

3. Shipbuilding and Marine Equipment

The corrosion resistance of brass plates makes them a key component material for ship propulsion systems, valves, and offshore platforms.

It maintains good mechanical properties in seawater environments, reducing maintenance frequency.

4. Decoration and Artistic Finishing

Due to its high surface gloss and ease of processing, brass plates are often used in architectural decoration, doors and windows, lighting fixtures, and various artistic sculptures.

Diverse decorative effects can be achieved through surface treatments such as wire drawing and polishing, combining functionality and aesthetics.

How to maintain and polish brass sheets to prevent loss of luster?

Brass Sheet Maintenance and Polishing Methods

1. Chemical Polishing Process

Prepare the polishing solution according to the instructions (operate at room temperature in a well-ventilated area). Immerse the brass sheet for 2–3 minutes, then rinse immediately to remove any residual chemicals.

After polishing, perform spraying or passivation treatment, and air dry in a cool, well-ventilated place to form a protective layer.

2. Additives to Enhance Luster

If the luster is still insufficient, add 1%–2% brightener or surfactant to the polishing solution to enhance the metallic luster.

If the desired result is still not achieved, replace the polishing solution to ensure the formula is fresh and effective.

3. Ultrasonic Polishing (or Electrochemical Polishing)

Place the brass sheet in a suspension containing abrasive particles and place it in an ultrasonic field. High-frequency oscillations achieve fine grinding, preventing workpiece deformation.

Ultrasonic polishing can be combined with chemical or electrochemical polishing to further enhance surface brightness and inhibit corrosion.

4. Post-treatment Protection

After polishing, immerse in a copper protectant for approximately 30 seconds to form an antioxidant film, significantly extending the gloss retention time.

Wear protective gloves during operation to avoid direct skin contact with the polishing solution; thoroughly clean and store in a cool place after polishing.
