Technical Q&A Summary

Q: Which material in the JF Bimetal series is most suitable for heavy-duty applications requiring maximum load resistance?

A: The CN-797 alloy is the primary choice for such requirements. It features a CuPb10Sn10 sintered layer with an alloy hardness of 80~120 HB.

This model achieves a 5-star rating for both high loading and anti-fatigue performance, supporting a maximum dynamic load of 150 N/mm².

Q: How does the lubrication type affect the performance limits of these bushings?

A: Lubrication significantly alters the operational thresholds. For instance, under grease lubrication, the Max PV limit for most models is 2.8 N/mm²·m/s.

However, when switched to oil lubrication, the Max PV limit increases substantially to 10 N/mm²·m/s, and the maximum speed can reach up to 10 m/s for the CN-799 model.

Q: What is the primary difference in lead content between CN-797 and CN-799, and how does this impact their performance?

A: According to the composition analysis, CN-797 contains 9.0~11.0% Pb, while CN-799 contains a much higher concentration of 21.0~27.0% Pb.

This higher lead content gives CN-799 a superior 5-star rating in anti-bite shaft properties and sliding performance,

though it results in lower hardness (45~70 HB) compared to CN-797.

Q: Are there lead-free or environmentally friendly options available in this series?

A: The CN-830 and CN-840 alloys are the more environmentally conscious choices, as their lead content is restricted to 0.1%.

Both models receive a 2-star rating for environmental protection. They utilize tin-bronze compositions (CuSn10 and CuSn6.5P)

and offer balanced 4-star ratings in abrasion resistance and load capacity.

Q: For high-speed applications, why might the CN-783 aluminum-based bushing be considered?

A: The CN-783 (AlSn20Cu) is specifically designed for high-velocity environments. It boasts the highest maximum speed limit in the series at 15 m/s under oil lubrication.

While its hardness is relatively low (30~40 HB), it maintains a 4-star rating for anti-bite shaft properties, making it ideal for specialized sliding applications.

Lock Washers & Fasteners Q&A Summary

Q: What material options are available for Wedge Lock Washers to ensure high-strength performance?

A: CHANNOV offers two primary material categories for Wedge Lock Washers: carbon/alloy steel options such as 65Mn, S60C, SK5, 60Si2Mn, and 51CrV4,

as well as stainless steel options including SS304, SS316, A2, A4, and Super Stainless Steel.

Q: Which surface treatment provides the highest corrosion resistance for steel DIN9250 washers?

A: While standard options like Plated Zinc and Black Oxide are available, Geomet® 500 Grade B offers the most robust protection, providing up to 1000 hours

of red corrosion resistance. This is significantly higher than white mechanical zinc plating, which typically offers 168 to 288 hours of resistance depending on the coating thickness.

Q: How do the finishing requirements differ between carbon steel and stainless steel DIN471 retaining rings?

A: Carbon steel DIN471 rings are typically finished with Plated Zinc, Black Oxide, Mechanical Galvanizing, or Phosphating to prevent rust.

In contrast, stainless steel versions (SS304, SS316, SS420) usually undergo Polishing to maintain their natural corrosion resistance and provide a clean aesthetic finish.

Q: What is the benefit of using Geomet® or Delta Protekt® coatings over traditional zinc plating for industrial fasteners?

A: Advanced coatings like Geomet® 321 and Delta Protekt® KL100 provide superior red corrosion resistance, ranging from 600 to 1000 hours,

whereas standard white electrolytical zinc plating may only offer 12 to 96 hours of protection. These high-performance finishes also offer a gray satin aspect,

which is preferred for heavy-duty industrial environments.

Q: Which materials are used for specialized spring components like DIN6796 and DIN2093?

A: These high-performance washers and disc springs are manufactured using specialized spring steels such as 60Si2Mn and 51CrV4,

or stainless steel variants like SS304 and SS316 to ensure consistent tension and durability under load.

Common Questions on Titanium Alloy Chemical Compositions

Q: What are the main chemical ingredients of TC4 (GR5) titanium alloy?

A: According to the GB/T 3620.1-2007 standard, TC4 (GR5) titanium alloy consists of 5.5–6.75% Aluminum (Al) and 3.5–4.5% Vanadium (V), with titanium (Ti) as the remainder.

For the TC4ELI version, the aluminum content is slightly tighter at 5.5–6.5% and vanadium at 3.5–4.4%.

Q: How does the impurity control differ between TA1ELI and TA1 industrial pure titanium?

A: TA1ELI (Extra Low Interstitials) has much stricter impurity limits than standard TA1. For instance, the maximum Iron (Fe) content for TA1ELI is 0.10% and Oxygen (O) is 0.10%,

whereas standard TA1 allows up to 0.20% Iron and 0.18% Oxygen.

Q: What is the unique composition of TA9 (GR7) and TA9-1 (GR11) alloys?

A: These alloys are characterized by the addition of Palladium (Pd) to improve corrosion resistance. TA9 (GR7) contains 0.12–0.25% Palladium, while TA9-1 (GR11) contains 0.12–0.26% Palladium.

Both maintain high titanium purity with standard interstitial impurity controls.

Q: Which titanium alloy grade includes Molybdenum (Mo) and Nickel (Ni) in its composition?

A: TA10 (GR12) titanium alloy specifically includes 0.2–0.4% Molybdenum (Mo) and 0.6–0.9% Nickel (Ni). This specific combination enhances the alloy's strength and resistance to crevice corrosion

in high-temperature environments.
