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.

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

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.
