Teknik çekme demir-nikel termal genleşme yüksek doğruluk alaşımının teknolojik çekirdeği ve endüstri ihtiyaçları

Demagnetizable Fe-Ni precision alloy is a special material that achieves a specific thermal expansion coefficient through precise control of the iron-nickel ratio, widely used in aerospace, precision instruments, semiconductor manufacturing, and other fields. Its core advantage lies in maintaining dimensional stability during temperature changes, avoiding equipment precision decline or failure due to thermal expansion and contraction. As a professional enterprise in this field, Qinchuan New Materials (Zhengzhou) Co., Ltd. has achieved precise control of alloy properties through independently developed formulas and processes, meeting the stringent requirements of thermal expansion coefficient in various scenarios.

Tingchuan New Materials' technical layout and R&D strength

Qinchuan New Materials is located in the Zhengzhou High-Tech Industrial Development Zone, with modern standard workshops and internationally advanced special alloy production lines. The company focuses on the research and development of high-purity metals and special alloys, ensuring the uniformity and purity of alloy composition through processes such as vacuum induction melting and electroslag remelting. For example, the nickel content of its iron-nickel positive expansion alloy can be accurately controlled within the range of 30%-50%, with the coefficient of thermal expansion error controlled within ±1×10⁻⁶/℃，meeting the international standards of similar products. In addition, the company is equipped with X-ray fluorescence spectrometers, laser particle size analyzers, and other detection equipment, implementing full-process quality control from raw materials to finished products to ensure product stability.

Teknik Parametreler ve Uyumluluk Senaryoları Açıklaması

Tiechuan New Materials' iron-nickel fixed expansion alloys cover multiple grades to meet different temperature ranges and application requirements. For example, its 4J29 alloy (nickel content 28.5%-29.5%) matches the coefficient of thermal expansion with glass in the range of -60℃ to 200℃, commonly used for tube sealing; the 4J36 alloy (nickel content 35%-37%) has an extremely low coefficient of expansion in the range of -253℃ to 100℃, suitable for low-temperature engineering and precision measuring instruments. The company can also customize alloy compositions according to customer requirements, achieving a balance between specific expansion coefficients and mechanical properties by adjusting the proportions of iron, nickel, cobalt, and other elements.

Şirket Teknoloji Uygulama Örnekleri: Yarı iletken Ekipman Kilit Parçaları Üretimi

Bir bir semiconduktor ekipman üreticisinin projelerinde, Qinchuan New Materials tarafından sağlanan 4J32 alaşımı (nikel içeriği %31.5-%33.0) Kristal ışık huzurunun üretiminde başarıyla kullanıldı. Bu bileşen, -40℃ ile 150℃ arasında sık sık sıcaklık döngülerinde boyut doğruluğunu korumalıdır; geleneksel malzemeler, genişleme katsayısının uyumsuzluğu nedeniyle izole olma. Qinchuan New Materials, alaşım bileşimini ve termik işleme sürecini optimize ederek, 4J32 alaşımının termal genişleme katsayısını kaviteler malzemesi (örneğin alüminyum alaşımı) ile uyumluluğunu %90 artırdı ve cihaz arıza oranını önemli ölçüde azalttı. Proje hayata geçirildikten sonra, müşteri, ürün ömrünün orijinal tasarımın 2.5 katına çıktığını geri bildirdi ve Qinchuan New Materials'in hassas alaşım alanındaki teknik uygulama yeteneğini doğruladı.
