High-Performance CrAl Sputtering Target for Hard Coatings, 99.8% Purity: The Ultimate Industrial Guide
I. Technical Specifications and Manufacturing Excellence
A superior CrAl Sputtering Target for Hard Coatings, 99.8% Purity is not merely a mixture of metals; it is a precisely engineered alloy. At Ti Time Company, we use the Hot Isostatic Pressing (HIP) process to consolidate Chromium and Aluminum powders, resulting in a target with near-theoretical density and ultra-fine grain structure.
Core Technical Profile:
Typical Stoichiometry: Cr-70at%Al (70% Aluminum atomic ratio).
Main Composition: Cr (45.2 ± 1) wt%.
Density: 3.76g/cm³ (High density prevents arcing during deposition).
Impurity Control: Strict limits on oxygen (< 2000 ppm), nitrogen (< 200 ppm), and iron (< 700 ppm) to ensure coating toughness.
II. Why Choose CrAl for Hard Coatings?
Using a CrAl Sputtering Target for Hard Coatings, 99.8% Purity allows manufacturers to create films that outperform traditional CrN or TiN coatings in several ways:
Exceptional Oxidation Resistance: The addition of Aluminum promotes the formation of a stable, protective Al₂O₃ oxide layer on the coating surface at high temperatures.
High Red Hardness: CrAlN coatings maintain their hardness even when the cutting tool reaches high temperatures during dry machining.
Superior Adhesion: Chromium-based nitrides are famous for their strong chemical bond to steel and carbide substrates, drastically reducing the risk of delamination under heavy loads.
III. Applications in High-Demand Industries
As a trusted supplier, Ti Time Company provides customized production of CrAl targets for various high-stress scenarios:
Precision Tooling: Enhancing the service life of drills, end mills, and taps used in high-speed machining.
Molding & Die Casting: Protecting injection molds and punching dies from wear and corrosion.
Automotive Components: Applying durable, low-friction coatings to engine parts and decorative trim.
IV. FAQ: Expert Insights on CrAl Sputtering Targets
Q1: Why is the 99.8% purity level significant for hard coatings? A: While semiconductor targets require higher purity, 99.8% purity is the industrial “gold standard” for hard coatings. It provides the necessary mechanical toughness while keeping the sputtering target price viable for high-volume tool production.
Q2: How does the Cr:Al ratio affect the coating performance? A: A higher Aluminum content (like our Cr-70at%Al) generally improves oxidation resistance and hardness. However, we offer customized manufacturing for different ratios (e.g., 50:50 or 60:40) depending on whether the user prioritizes toughness or thermal stability.
Q3: Is DC magnetron sputtering suitable for CrAl targets? A: Yes. Because CrAl alloys are electrically conductive, they are perfectly suited for DC or pulsed DC magnetron sputtering. This allows for high deposition rates and excellent film density.
Q4: What are the typical impurity limits for a high-quality CrAl target? A: For a reliable CrAl Sputtering Target for Hard Coatings, 99.8% Purity, impurities like Iron (Fe) should be <700 ppm and Silicon (Si) <500 ppm. High oxygen or carbon content can lead to brittle coatings that fail prematurely.
Q5: Can Ti Time Company produce rotary CrAl targets? A: Absolutely. We provide both planar and rotary (tubular) configurations. Rotary targets are highly recommended for large-scale industrial coating lines due to their higher material utilization and longer campaign times.
