AMETEK Specialty Metal Products employs a wrought powder metallurgical process to manufacture custom gauge and width strip materials used as the outside sheathing of flux cored wire and metal cored welding wire.
Advantages
Our high purity process allows production of wire sheathing materials with significant advantages for flux cored welding wire producers, compared to a conventional casting process. These include:
Very high ductility
Tight and repeatable chemistry control
Availability of unique and custom chemistries
High purity material for improved tool and die life
Corrosion, wear and high temperature resistant
Short lead times and small batch sizes

Chemistry Control
We tightly control the chemistry of the incoming raw materials to ensure that trace elements are kept to a very low level. Our wrought powder metallurgy process allows chemistry flexibility
Laserage is widely regarded as the medical industry-leading expert in laser contract manufacturing. Since 1979, we have been leading the way in the field of custom laser processing, providing medical device component fabrication with numerous laser manufacturing capabilities.
The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together.
Welded Processes
Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement.
The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include

HPM® C 276 is a Nickel-Molybdenum-Chromium-Tungsten alloy with a high level of corrosion resistance. A low carbon content enables the alloy to resist intergranular corrosion at weld joints. These attributes make it an important alloy for the most severe chemical processing applications. such as use in metal diaphragms for aerospace sensors and burst discs.
The alloy is readily formed from the annealed temper.All standard welding methods except oxy-acetylene can be used for joining.

Welded and redrawn tube manufacturing employs elements of both the welded and seamless processes.
A welded and redrawn tube is welded in a conventional manner but then transferred to our seamless mill, located in the same factory. Here the product is redrawn to achieve a welded and redrawn finish.
The objective of redrawing is to achieve homogenisation of the weld following annealing by cold working. This refines the structure of the weld resulting in improvements that include:
Better corrosion resistance
Improved fatigue life
Higher mechanical integrity

Stainless steel grades cover a wide range of compositions which result in the generation of a variety of microstructures and mechanical properties. This group of alloys is useful for the replacement of mild steel in structures and components.
Stainless Steel tubes manufactured by Fine Tubes have an excellent combination of corrosion resistance, metallurgical stability and formabilityStainless steels are favoured because they are very cost effective. They also have an excellent combination of corrosion resistance, metallurgical stability, formability, and are easily welded. Their fabrication characteristics, good mechanical properties and attractive finished appearance make high quality stainless steel tubing a popular choice in a range of industries.

Our standard offering of nickel chrome strip products contain a chrome percentage ranging from 20%, 30% and 35% chrome (balance nickel). Silicon can also be added to the product to promote de-oxidation during the welding process
The 35% chrome (AMETEK 835) is one of the highest chrome containing products offered in the industry and our high purity process allows for elongations above 45% for even those products containing silicon additions between 1% and 2%.

AMETEK Specialty Metal Products has applied the high purity wrought powder compaction process to Ductile Cobalt Alloys in order to produce multiple ductile cobalt strip products generally used by weld wire manufacturers as sheathing for flux cored and metal cored hardfacing materials. These alloys range from 80 to 95% cobalt with Iron or Iron-Nickel additions to improve ductility for drawing operations.
Our weld wire sheathing material is used in both flux cored wire and metal cored welding wire processes. The wire sheathing is formed into a tubular product by our customers and the center of the tube contains the ‘fill’ (flux, metal powders, etc) to bring the wire to the desired chemistry.
The finished wire is used across a wide breadth of industries in processes such as:
Submerged Arc Welding (SMAW)
Gas Metal Arc Welding (GMAW)
Wire Arc Thermal Spray
Flux cored welding wire producers use our metal sheathing materials to prepare finished wire for thermal spray and in surfacing applications, in high temperature and corrosive environments.
Cobalt
Our Ductile Cobalt Alloys are used to produce wire to hardface applications in the construction, mining, and oil and gas industry. Our proprietary process allows us to offer high Cobalt containing products (91% Cobalt or more) while maintaining a highly ductile strip for wire forming.
