Bronze wire mesh is a versatile material with a wide range of applications, from industrial uses as a liquid filter to decorative architectural projects. With its unique blend of strength, durability, and aesthetic appeal, bronze wire mesh has become increasingly popular in various industries. Weave Types and Mesh Size Bronze wire mesh is available in various weave types, each offering different characteristics to suit specific applications. The most common weave types include plain weave, twill weave, and Dutch weave. Mesh size refers to the number of openings per inch in the wire mesh. It determines the filtration capacity and can vary based on the application requirements. Mesh sizes typically range from 2 mesh to 400 mesh, with smaller sizes suitable for finer filtration and larger sizes for more coarse applications. Classification and Application Bronze wire mesh can be classified based on its material composition, such as phosphor bronze or aluminum bronze, and its specific application. Liquid Filter Use: Bronze wire mesh is widely employed as a liquid filter due to its excellent durability and corrosion resistance. It effectively removes impurities from liquids while maintaining high flow rates. Common applications include filtration in chemical processing, oil refining, pharmaceutical production, and water treatment. The choice of mesh size depends on the desired level of filtration and the type of contaminants being targeted. Decorative Architectural Use: Bronze wire mesh has gained popularity in the architectural world for its aesthetic appeal and versatility in creating unique designs. It can be used for interior and exterior applications, such as decorative facades, partitions, balustrades, and ceilings. The bronze mesh adds a touch of elegance, allowing light and air to pass through while providing privacy and protection.

Woven copper meshes are woven from a variety of copper and copper alloy wire materials. We manufacture and fabricate woven copper mesh screens for a variety of industries including test sieves, filter, EMI/rfi shielding, heat treating and more. Common material content: Red copper wire (99.9% pure copper content), phosphor copper wire (85%-90% copper, 5%-15% tin). Weaving patterns: Plain weave, twill weave, dutch plain weave, dutch twill weave. Plain weave -Each warp wire crosses alternately above and below each weft wire. Warp and weft wires generally have the same diameter. Twill Weave -allows a thicker wire and is suitable for heavy meshes. The wire position of twill weave wire mesh is less stable compared with plain weave. Dutch Plain Weave -similar to plain weave, while the warp wires are thicker and packed more closely together. This type of woven wire mesh is mainly used as industrial filter cloth. Dutch Twill Weave -combination of dutch weave and twill weave. It is similar to twill weave, but the warp wires are thicker and packed more closely together. This type enables a strong wire cloth with super fine filtration. for fine filtration. Five Heddle Weave -smooth top surface and an open lower surface. It is ideal to withstand high mechanical strain and excellent filter performance. Reverse or Reinforced Dutch Weave -the same as dutch weave except the warp and weft wires are reversed. the weft wires are thicker than the warp wires. the opening of the two nearby orientated wires (warp wires or weft wires) at dutch weave is difficult to define.

Brass woven wire cloth is a versatile material known for its durability, corrosion resistance, and aesthetic appeal. It finds applications in a wide range of industries, including filtration, sieving, screen printing, and decorative purposes. Weave Types: Plain Woven, Twill Woven, and Dutch Woven Brass woven wire cloth is available in various weave types, each offering distinct characteristics and applications. Plain Woven: Plain woven brass wire cloth is the most common and simplest weave type. It features a simple over-and-under pattern, resulting in a square mesh with uniform openings. This weave type provides good strength and excellent filtration capabilities, making it suitable for general-purpose applications such as particle filtration and separation. Twill Woven: Twill woven brass wire cloth is characterized by a diagonal pattern created by passing the weft wire alternately over and under two or more warp wires. This weave type offers greater strength and allows for finer mesh sizes. Twill woven brass wire cloth is commonly used in applications that require precise filtration, such as fine particle separation and liquid filtration. Dutch Woven: Dutch woven brass wire cloth is characterized by a combination of fine mesh openings and a relatively high wire density. It has a reverse twill weave pattern with a smaller wire diameter used as the weft wire and a larger wire diameter used as the warp wire. Dutch woven brass wire cloth provides excellent filtration performance and is commonly used in applications where fine filtration and high flow rates are required, such as pressure and vacuum filters.

RFI (radio frequency interference) shielding wire mesh is usually adopted by electronic equipment manufacturers in electro magnetic interference (EMI) and radio frequency interference (RFI) to protect sensitive digital circuits from external radiation, while limit the potentially harmful radiation emitted by their products. RFI (radio frequency interference) shielding is a method of protecting electronic devices and technological systems from damaging electromagnetic interference (EMI). One of the most effective materials for defending against these electromagnetic waves is metal mesh — particularly copper woven wire cloth. Typically, EMI is generated from large electronic equipment to smaller devices. However, small electronics can also transmit waves that negatively affect other systems. As a result, electronics tend to malfunction due to: The suppression of radio signals within a device; Internally generated emissions, which interfere with functionality; Ambient interference from the outside, which impacts operation efficiency. Protective metal wire cloth is essential for safeguarding valuable electronic equipment and ensuring it runs properly. One of the oldest measure of this solution is the Faraday cage, wrapped in conductive mesh material. The fabricated item was invented by Michael Faraday in 1836 to block electromagnetic fields.
