Alleima, a global leader in precision steel strip manufacturing, provides the foundation for critical applications across industries through its comprehensive product portfolio and advanced manufacturing processes.

Alleima specializes in producing high-precision steel strips for diverse applications including compressors, cutting tools, medical instruments, razors, springs, doctor blades, shock absorbers, and various industrial components. The company's products are distinguished by their superior mechanical properties, exact dimensional control, and versatile surface treatments.

Alleima's precision steel strip portfolio encompasses multiple steel grades and specifications, each optimized for specific applications.

This specialized material forms the backbone of various valve types including reed valves, check valves, plate valves, relief valves, and safety valves. Alleima's hardened and tempered compressor valve steel offers exceptional fatigue resistance, wear characteristics, and corrosion protection, ensuring reliable operation under demanding conditions. The material's precise dimensional tolerances and superior surface quality contribute to improved sealing performance and response times.

Ideal for manufacturing cutlery, kitchen knives, surgical instruments, and industrial blades, Alleima provides various annealed or cold-rolled stainless chromium steels in coil or straight lengths. These materials combine excellent hardness, toughness, and corrosion resistance with superior machinability for subsequent forming, heat treatment, and sharpening processes.

Meeting stringent biocompatibility requirements, Alleima's medical-grade steel strips are used in bone saws, surgical instruments, orthopedic implants, and microtome blades. The materials feature exceptional corrosion resistance and sterilizability, with precise dimensional control and surface treatments that enhance surgical precision while minimizing patient trauma.

Alleima's Alleima® 13C26 martensitic stainless chromium steel, delivered as cold-rolled strip with tight tolerances, forms the basis for high-quality shaving blades. The material's extreme hardness and wear resistance maintain edge sharpness, while superior flatness ensures optimal skin contact for comfortable shaving.

Used in automotive suspension systems, industrial equipment, and electronic components, Alleima's spring steel portfolio includes stainless steels, precipitation hardening steels, and nickel alloys with various size and coating options. These materials offer excellent elastic limits, fatigue strength, and corrosion resistance for reliable long-term performance under cyclic loading.

Essential for printing applications, these high-wear-resistance strips feature precise dimensional control and consistent straightness for optimal ink removal. Specialized surface treatments enhance wettability and reduce ink adhesion, while careful edge preparation prevents plate damage.

Carbon and stainless steel strips for high-performance damper shims provide exceptional fatigue resistance and corrosion protection for extreme operating conditions. Precise hardness and dimensional control ensure consistent damping characteristics.
