      Foire Aux Questions (FAQ)<\/h2>\n

      1. Qu’est-ce que le laiton sans plomb et en quoi diff\u00e8re-t-il du laiton standard ?<\/h3>\n

      Le laiton sans plomb est un alliage cuivre-zinc avec une teneur en plomb limit\u00e9e \u00e0 0,25 % ou moins en masse. Le laiton de d\u00e9colletage standard (C36000) contient 2,5\u20133,7 % de plomb comme adjuvant d’usinabilit\u00e9. Les variantes sans plomb utilisent du silicium, du bismuth ou du bore comme substituts pour maintenir les performances d’usinage tout en respectant les normes environnementales mondiales.<\/p>\n

      2. Quelle nuance de laiton sans plomb Conex Metals recommande-t-il pour les applications \u00e9lectriques ?<\/h3>\n

      Pour les applications \u00e9lectriques n\u00e9cessitant une haute conductivit\u00e9 et la conformit\u00e9 RoHS, Conex Metals recommande le C69300 (EnviroBrass III) ou le C36000-LF. Le C69300 offre un bon indice d’usinabilit\u00e9 (80 %), une conductivit\u00e9 \u00e9lectrique ad\u00e9quate (environ 26 % IACS) et une excellente r\u00e9sistance \u00e0 la corrosion.<\/p>\n

      3. Quelle est la teneur en plomb de vos pi\u00e8ces en laiton sans plomb ?<\/h3>\n

      Toutes les pi\u00e8ces en laiton sans plomb fournies par Conex Metals respectent une teneur en plomb maximale de 0,25 % (m\/m) ou inf\u00e9rieure selon la nuance s\u00e9lectionn\u00e9e. Les nuances C69300 et C87850 sont typiquement \u00e0 moins de 0,09 % Pb, satisfaisant aux exigences les plus strictes.<\/p>\n

      4. Vos pi\u00e8ces usin\u00e9es en laiton sans plomb sont-elles conformes \u00e0 la directive RoHS ?<\/h3>\n

      Oui. Toutes les pi\u00e8ces en laiton sans plomb fabriqu\u00e9es par Conex Metals sont conformes \u00e0 la directive RoHS 2011\/65\/UE et \u00e0 son amendement 2015\/863\/UE.
