Discover the n° 1 alternative
to stainless steel medical wires
Bezinal® coated steel wires for use in medical applications
Meeting FDA and EFSA quality standards, Bezinal® XP and Bezinal® XC zinc-aluminum coated high carbon steel wires are an economical alternative to stainless steel for the production of medical springs in non-invasive surgical instruments such as in aerosols, inhalers, retractable syringes and dosing or auto-injector pens.
While Bezinal® XP excels in corrosion and cathodic protection, Bezinal® XC is characterized by a very stable coating integrity that can withstand heavy deformation without losing overall performance. Bezinal® XP and Bezinal® XC address several market demands like the increased need for miniaturization, prolonged shelf life and cost-efficient production.
Ideal for small, light and complex medical tools
Bezinal® XP and Bezinal® XC coated steel wires meet the growing need for smaller, lighter and more complex medical tools. The wires offer improved material properties over stainless steel the production of medical springs; Not only do they exhibit extended corrosion performance; they also demonstrate improved material properties including a 17% higher e-modulus and a higher maximum solid stress (+6% for non-stressed and up to +9% for pre-stressed springs) when applying standard designs. Moreover, it’s generally accepted that (pre-coated) high carbon wire solutions show better fatigue performance than stainless alternatives.
As a result, these wires allow you to:
meet tight tolerances
produce smaller spring dimensions
with higher spring rates
maintain high accuracy and repeatability
Easy to process, with low production costs
Unlike galvanized wires, Bezinal® XP and Bezinal® XC wires have very stable coatings layers. They create less flaking and dust during coiling and deformation, leading to much more cost-efficient production process:
creates a cleaner working environment
reduces frequency of machine cleaning
allows production at higher coiling speeds
eliminates the need for expensive post-coating processes

Due to high corrosion resistance and cathodic protection ability, Bezinal® XP and Bezinal® XC are not susceptible to pitting corrosion and are capable of protecting defects for a prolonged time. Compared to galvanized or phospated wires, Bezinal® XC coated wires last about 10x longer and Bezinal® XP wires up to 20x longer, without additional post-coating.
