CA 2287440

There is provided a tin brass alloy having a grain structure that is refined by the addition of controlled amounts of both zinc and iron. Other metallic elements that undergo peritectic decomposition in a tin brass alloy, such as cobalt, iridium, niobium, vanadium and molybdenum may substitute for from a portion to all of the iron. Direct chill cast alloys containing from 1 % to 4 %, by weight of tin, from 0.8 % to 4 % of iron, from an amount effective to enhance iron initiated grain refinement to 20 % of zinc and the remainder copper and inevitable impurities are readily hot worked. The zinc addition further increases the strength of the alloy and improves the bend formability in the "good way", perpendicular to the longitudinal axis of a rolled strip.

L'invention concerne un alliage de laiton à l'étain dont la structure granulaire est affinée par l'addition de quantités contrôlées de zinc et de fer. D'autres éléments métalliques subissant une décomposition péritectique dans un alliage de laiton à l'étain, tel que le cobalt, l'iridium, le niobium, le vanadium et le molybdène, peuvent remplacer une partie ou la totalité du fer. Les alliages coulés par refroidissement intense et direct, qui contiennent 1 à 4 % en poids d'étain, 0,8 à 4 % de fer, du zinc en une quantité comprise entre une quantité efficace pour améliorer l'affinage des grains amorcé par le fer et 20 %, le cuivre restant et les impuretés inévitables, sont immédiatement déformés à chaud. L'addition de zinc augmente la résistance de l'alliage et son aptitude à une déformation par flexion "correcte", c'est-à-dire perpendiculaire à l'axe longitudinal de la bande laminée.
