The thickness of the strip material ranges from 0.01mm to 3.5mm.
The diameter of the wire material is from 0.009mm to 12mm.
The bar material has a diameter of over 5mm.
The sheet material has a width of no more than 1000mm.
Customization process
The clients familiar with the material only need to provide the necessary grade and specifications of the alloy.
As for those unfamiliar with the material, we can determine the specification and final size of the alloy material according to the application range provided by customers. At the same time, based on different customers, we can offer the specific parameters, production process, pictures and other information of the material for confirmation.
Successful custom case
Inquiry stage
One customer is a manufacturer of braking resistors used in railway applications, but he is not certain about the material and price of the resistor.
Discussion stage
Once we decided on the application needs, we provided four kinds of material to choose from, including nichrome 20/35, stainless steel 321, FeCrAl 0Cr13Al4 and stainless steel 430.
Determination stage
We supplied the properties, costs and functions of various materials to the customer. Finally, they chose the FeCrAl 0Cr13Al4.
Placing order
After the confirmation of materials and specifications, we produced a sample of 100kg, which passed the repeated tests over 3 months by customer. And then after a half years of durability experiments, this customer began to purchase in large quantities with over 5 tons per month.
Manufacturing equipment
OHMALLOY’s manufacturing workshop is equipped with equipment for alloy melting, rolling, wire drawing, annealing, and slitting to support the processing and customization of alloy wire, strip, and rod. Processing steps are selected according to the characteristics of different alloys and customer requirements for dimensions, delivery condition, and material performance. Relevant inspections help verify that the materials meet the agreed specifications, supporting sample validation and subsequent batch supply.
