Stainless Steel
Read
Inox steel, a low-carbon alloy of iron with at least 10.5% chromium, forms a self-repairing protective film through passivation. It offers excellent resistance to staining, corrosion, and high temperatures. In automotive, aviation, medical, and food <a href="https://www.geminiwiremesh.org/industries/">industries</a>, it is preferred for its strength, corrosion resistance, and hygienic properties. Various wire options are available with different characteristics.

Copper & Copper Alloys (Brass)
Read
Copper, a soft and ductile metal, can be easily alloyed. It exhibits high thermal and electrical conductivity, corrosion resistance, and can withstand extreme environments. Copper finds applications in high-tech uses like EMC shielding and electrical connections, as well as in low-tech applications like cleaning mesh and antibacterial filters.

Aluminium
Read
Aluminium is a lightweight, silvery-white metal with high strength-to-weight ratio. It is malleable, ductile, and non-magnetic. Widely used in automotive and aerospace industries for its strength:weight advantage, as well as in military and energy applications where lightweight structures are needed, such as composite moulding cores.

Polymer (PPL, PE, PEEK)
Read
Knitted mesh can be made from various natural or synthetic polymers. Synthetic polymers offer thermal stability, flexibility, insulation, strength, and chemical resistance. Commonly used polymers include Polypropylene, Hostaflon®, and Teflon® for applications such as cleaning products and drying pads.

Galvanised-Steel
Read
Galvanizing is the process of applying a protective coating (usually zinc or magnesium) to prevent rust on steel or iron. It enhances corrosion resistance while retaining the strength of carbon steel. Galvanized steel finds applications in industries like foundries and food processing, offering cost-effective corrosion-resistant solutions.

Multifilaments
Read
Gemini Wiremesh can knit multiple strands or filaments into mesh. Multi-filament mesh has several strands per loop, co-knit mesh combines different materials, and multi-strand mesh uses phased layers. Multi-layer mesh involves knitting one mesh sock inside another.

Mineral (Glass, Silica)
Read
Glass and graphite minerals can be infused into knitted mesh structures to attain specific properties defined by customers. With temperature and chemical resistance, as well as self-lubricating qualities, they find applications in arduous environments. Examples include mesh gaskets, furnace seals, and gland packing in various exhaust, sealing, and valve systems.

Carbon-Steel
Read
Carbon steel encompasses non-stainless steel and various alloy steels, making it the widely used metal-based material. Increasing carbon content (up to 2.1% by weight) through heat treatment enhances hardness and strength while reducing ductility. It is cost-effective, available in different grades, and used in applications prioritizing durability over corrosion resistance, often with galvanic coatings for shorter life cycles.

Nickel & Nickel Alloys (Monel, Inconel, Incolloy, Haynes)
Read
Nickel, known as Monel® alloys, forms versatile alloys with most metals, particularly copper. It offers high corrosion resistance (especially to seawater) and strength at high temperatures. Nickel is used for plating or alloying to protect metals, finding applications in chemical, marine industries, electrochemical equipment, marine engineering, and gas turbines for anti-vibration components in harsh environments.

Plated and Insulated Copper
Read
Coated or plated copper wire achieves specific properties by applying thin layers of insulating, conducting, or protective materials. It can provide corrosion resistance (e.g., tinned), electrical conductivity (e.g., silver plated), insulation (e.g., plastic coated or enamelled), or tarnish resistance (e.g., gold, nickel, or silver plated). Common applications include EMC, RFI, cable screening, and jewelry manufacturing, offering formability, resistance to tarnishing, and a variety of colors for aesthetics.

Precious Metals
Read
Knitting wire is available in pure form or alloys of precious metals like silver, gold, and platinum. Apart from their aesthetic and workability properties, these metals exhibit inertness, stable temperature, and corrosion resistance, making them suitable for harsh environments where common metals degrade. They find applications in jewelry production, such as bracelets and brooches, while platinum mesh has been used in experimental surgical implants due to its stability in the human body.

PTFE, FEP (Teflon, Hostaflon)
Read
PTFE and FEP, commonly known as Teflon®, are tough, flexible, non-resilient thermoplastics with excellent thermal (260-325°C), insulation, chemical resistance, UV/weathering resistance, and hydrophobic properties. They find applications in challenging process industry environments like gas/liquid or liquid/liquid separation, demister, and coalescer applications.

Specialist Wire & Super Alloys
Read
Wires commonly used include titanium, nickel, and alloys like Fecralloy®, Hastelloy®, Incoloy®, and Inconel®. They possess mechanical strength, surface stability, resistance to thermal creep, high temperatures, corrosion, and oxidation. Pure titanium and nickel find applications in chemical or electrochemical uses, while Fecralloy® is suitable for electrical heating elements at high temperatures.

Coated Steel
Read
Steel wire coatings, such as metals (zinc, nickel), plastic (PVC), enamels, oil, and paint, modify properties like corrosion resistance and electrical conductivity. Applications range from security blankets made with insulated wire for triggered alarms to specialized uses altering physical properties while retaining strength.

Yarns
Read
Yarn materials like glass fiber, carbon fiber, and plastic filaments can be transformed into knitted mesh structures. The mesh inherits properties of the processed yarn, offering lightweight, durable, temperature and corrosion-resistant structures. Applications include "fog harvesting" mesh for capturing water from cloud mist in low rainfall areas, especially in the southern hemisphere.
