Abstract

본 발명은 브라운관용 새도우 마스크 재질인 인바 합금(Invar alloy)에 바나듐(V)을 첨가하여 항복강도를 낮추고 탄성계수를 증대시켜 성형성을 향상시키는데 적합한 새도우 마스크에 관한 것으로, 니켈(Nl)30∼40중량%, 바나듐(V)0.01∼0.09중량%이고 나머지는 실질적으로 철(Fe)로 이루어지는 것을 특징으로 하는 새도우 마스크재료에 관한 기술이다.The present invention relates to a shadow mask suitable for improving moldability by adding vanadium (V) to an Invar alloy, which is a shadow mask material for CRT, to lower yield strength and increase elastic modulus. 40% by weight, vanadium (V) 0.01 to 0.09% by weight, the remainder is a technique relating to the shadow mask material, characterized in that substantially consisting of iron (Fe).
