10. Inconel Round Wire & Strip
Key Characteristics: strong, high temperature resistance, corrosion resistant, expensive
- Springs: Given inconel is known for its exceptional strength and resistance to extreme environments, it may be the ideal material for springs in engines, turbines, and exhaust systems where high temperatures are prevalent, there is a high likelihood of exposure to harsh chemicals, or where high load-bearing capacity is required.
- Wire Forms: Inconel wire forms are great for applications where both high-temperature resistance and structural integrity are crucial. Examples include medical devises, safety-critical applications because these wire forms maintain their shape under continuous high-temperature, high-stress environments.
- Stampings: Although quite rare, stampings made from inconel would include the key characteristics listed above and be most effective in demanding applications.
11. Stainless Steel Round Wire
Key Characteristics: durability, corrosion resistant, aesthetic appeal, hygenic qualities, heat resistance
- Springs: Stainless steel round wire is highly versatile and used in applications where a balance of strengh, corrosion resistance, and aesthetic qualities are needed. Examples spring applications include automotive and aerospace suspension systems, medical devices due to hygenic properties and biocompatability, and electronic devices requiring precise and durable springs like switches and relays.
- Wire Forms: Similar to springs, stainless steel wireforms are used across various industries including medical, firearm, household appliances, and even marine applications given the material’s resistance to saltwater corrosion.
- Stampings: Although stampings are not typically ever made from round wire, some stainless steel round wire components are well suited to run on fourslide equipment. Examples include small, high volume components often used in electronic or aerospace applications.
In summary, the choice of material for springs, wire forms, and stampings depends on the specific requirements of the application, including factors like strength, corrosion resistance, formability, and cost-effectiveness. Each material has its own set of advantages and limitations, allowing manufacturers to select the most suitable option for their particular needs.
