Properties of knitted wire mesh
knitted wire mesh has distinct advantages over most competitive materials. Because each loop acts as a small spring when subjected to tensile or compressive stress, knitted metal has an inherent resiliency. If it’s not distorted beyond its yield point, the material will resume its original shape when the stress is removed. Even when it’s compressed into a special shape, a high degree of resiliency is retained. Varying the knitted structure, wire diameter, wire material and forming pressure used to create the part can control this characteristic.
knitted mesh also provides high mechanical damping characteristics and non-linear spring rates. Vibration and mechanical shock can be effectively controlled to eliminate the violent resonant conditions and provide ample protection from dynamic overloads.
In compressed form, knitted metal can handle shock loadings up to the yield strength of the material itself. The load may be applied from any direction—up, down or in from all sides.
Our application engineers have the experience to determine the optimum density of compressed units within the range of 10% to 70%. This is important in applications such as liquid filtration and noise attenuation where flow resistance is critical.
When compressed, layered, calendared or wound knitted metal presents a “tortuous” path to liquids or gasses flowing through it. This increases filtration capability and particle retention capacity.
Among the most important property of knitted mesh tube units is the material itself. By careful selection of the material or combinations of materials, Metal Textiles can custom engineer solutions best suited for our customer’s application—be it corrosive, ultra-high or cryogenic temperature, high pressure, radioactive, dirty, oily or other extreme conditions.
