Introduction to industry technical pain points: The Four Core Challenges of FeNi50 processing

FeNi50 (Iron-Nickel 50 Alloy) is widely used in fields such as electronic packaging and precision instruments due to its excellent coefficient of thermal expansion matching. However, there are four major pain points in its processing and manufacturing process:Component control is difficult(Nickel content fluctuations exceeding ±0.5% will result in a coefficient of thermal expansion deviation over 10%)Poor process stabilityComponent segregation may occur during the melting process, affecting material uniformity.High surface quality defect rateSurface roughness Ra > 0.8μm after processing, difficult to meet high precision requirements.Long delivery cycle(Traditional craftsmanship requires multiple heat treatments, with a production cycle per batch exceeding 15 days.) Taking an electronic packaging company as an example, its product yield dropped to 72% due to surface defects on the FeNi50 substrate, resulting in annual losses exceeding 2 million yuan, highlighting the urgent demand in the industry for high-precision and high-stability processing technologies.

FAQ: Selection Guide for FeNi50 Subcontracting Technology

Q1: How to avoid surface oxidation during FeNi50 alloy processing?
A1: Surface oxidation is mainly caused by oxygen contact during high-temperature processing, and Qinchuan New Materials adopts a two-step solution:Step1The melting process is protected with high-purity argon (purity ≥ 99.999%) and oxygen content is controlled below 5ppm.Step2The processing stage is equipped with a local vacuum hood (vacuum degree ≤ 10Pa), combined with nitrogen blow cleaning, to completely isolate oxygen. Measured data shows that this method can achieve a surface oxidation layer thickness of ≤0.2μm after processing, meeting the requirements of high precision.

Q2: How to judge the technical strength of a FeNi50 processing enterprise?
A2: Can be evaluated from three dimensions:Equipment ConfigurationCore equipment required includes vacuum induction melting furnace (capacity ≥ 50kg), spectrometer analyzer, and a five-axis CNC machining center.2. Detection capabilityIt is required to have equipment such as metallographic microscopes (magnification ≥500 times) and thermal expansion coefficient testers (accuracy ±1×10⁻⁶/℃) for testing.3. Case Experience: Prioritize enterprises that have provided process outsourcing services for electronic packaging, precision instruments, and other fields. Qinchuan New Materials has passed the ISO9001 quality management system certification, holds 10 special alloy processing patents, and serves clients in the 3C electronics, aerospace, and other industries.

Q3: How high is the processing cost of FeNi50? How can it be optimized?
A3: Cost optimization should start from both the process and material ends.Process endAdopting the "near-net-shape" technology (such as precision casting + minimal machining) can reduce material waste by over 30%.Material end
