The term "alloy surcharge" refers to an extra charge paid for certain raw materials. This surcharge is often calculated as a result of fluctuating world market prices. The need for alloy surcharges arises from the fact that prices for metals can fluctuate widely due to their rarity, demand, and other market-related factors. Therefore, such surcharges are a means for manufacturers to compensate for price fluctuations in raw material costs, and they allow transparent pricing to the customer.

If there are different wires with different lengths in a strand section with many wires, the longer wires create sack-like structures.

Gauge value, often referred to simply as "caliber," refers to the vertical distance between the highest point of a shaft and the lowest point of a valley in a crimped or fluted wire profile. In wire manufacturing, controlling the crimp depth can be important as it affects the mechanical properties, surface roughness and other physical aspects of the final product. A consistent and precise crimp depth ensures a uniform quality of the wire and is often critical for special applications where the shape and surface finish of the wire are important.

During a cutting process, high pressures and the resulting heat can lead to undesirable cold welding, which has a negative effect on the separation of the wires.

Curvature tolerance refers to the maximum permissible degree of deviation in the straightness of a wire during and after manufacture. It indicates the degree to which a wire may bend without failing to meet specified quality and functional standards.

During the wire manufacturing process, the material may experience varying degrees of curvature. This can happen due to various factors, such as temperature changes, stresses in the material, or external influencing factors during the production process. The curvature tolerance ensures that these deviations remain within acceptable limits. If a wire exceeds the specified curvature tolerance, this can lead to problems in further processing or in the end application. Therefore, monitoring and maintaining the curvature tolerance is an important quality assurance parameter in wire production.

In wire manufacturing, gear crimping refers to an irregularity or distortion in the surface structure of a wire caused by drawing the wire through toothed rollers or gear-like mechanisms. The wire is formed by passing through these geared structures.

When cutting or processing wire, undesirable small frays or burrs may occur at the end of the cut, known as "hooks". These can affect the quality and functionality of the wire and pose a safety hazard in some applications. A clean and precise cut and subsequent deburring procedures can help minimize hooking.

Multiple crimp refers to the fact that the wire has not just a single crimp or curve, but multiple ones arranged in a repeated sequence along its length. This can affect both the function and appearance of the wire, allowing it to meet specific technical requirements or design aesthetics.

In wire manufacturing, oil tempering refers to a special process for heat-treating wire. In this process, the wire is first heated to a certain temperature, which varies depending on the type of steel, and then quenched in oil. This process changes the microstructure of the metal to achieve certain desired properties.

Quenching in oil instead of water or other media provides slower cooling of the wire, resulting in a finer and harder microstructure. This improves the wire's mechanical properties, such as tensile strength, hardness and wear resistance, while minimizing the risk of distortion or cracking that can occur with faster cooling methods.

Oil tempering is particularly used for wires used in high stress applications, as it provides a balance between hardness and toughness.

A pin-crimped wire is a wire that has undulating bends or curves along its length. These undulations are created by special machines or devices that guide or press the wire around a series of pins to create the desired wavy structure.

In wire manufacturing, pin-crimped wire is often used for special applications or in products that require flexibility while maintaining some dimensional stability. The crimp can help the wire stay in place or conform better to specific shapes without losing its structural integrity.

• The crimp can be created in different sizes and distances.
• Crimping can give the wire increased flexibility and ductility.
• When producing pin-crimped wire, the quality of the original wire material must be taken into account, as the crimping process can stress the wire and change its properties.

The "Single krimp" refers to a crimped structure in which each wire has a uniform, repeated wave along its entire length. Gear crimped wires are particularly useful when a crimp with high precision and consistency along its entire length is required. The gear in this context refers to the tool or machine used to create the wave in the wire, with the gear determining the shape and size of the wave.

The wave length generally refers to the distance between two successive points of a wave that are in the same phase, for example from one wave crest to the next.

Wire descaling is an industrial process aimed at removing oxide layers or scale from the surface of metal wires. These oxide layers can form during the manufacturing process or due to environmental influences and affect the quality and functionality of the wire.

During the rolling or drawing process of metal, especially steel, a thin layer of metal oxides known as scale is formed on the surface. This scale can affect the mechanical properties of the wire, hinder its further processing and cause undesirable effects in the final application. Therefore, it is often necessary to remove the scale before further processing or application of the wire.

Descaling not only ensures the quality of the end product, but also improves the efficiency of subsequent manufacturing processes, as a descaled wire is easier to shape, weld and coat.
