Comprehensive Analysis Report on Service Advantages of Our (Jiasheng beryllium copper) Factory

Customized service capability

Special specification customization

We can provide custom phosphor bronze sheet products with ultra-thin specifications (0.05mm thickness) and ultra-wide specifications (up to 1200mm). We also support special length customization (up to 3000mm) and special-shaped cutting (such as laser cutting, stamping forming, etc.).

Typical customization cases include ultra-thin specifications for electronic connectors (0.05 - 1.2mm) and high-flatness sheet materials for bearing bushings (5 - 20mm thickness).

Variety of material grades

Chinese standard grades: QSn4-0.3, QSn6.5-0.1, etc., in accordance with GB/T 4423-1992 standard

Japanese standard grades: C5191, C5210, etc., in compliance with JIS H3270-2006 standard

American standard grades: such as C51100, etc., in accordance with ASTM B103 standard

Process customization

Offer various surface treatment options (such as grinding and polishing to Ra0.2μm, electroplating with 5-20μm coating, etc.)

Support special heat treatment processes (such as uniform annealing at 650°C - 750°C) to improve material performance

Professional technical support system

The copper alloy factory has established a comprehensive technical support service

Technical Team

Equipped with a professional engineering team, providing technical support such as material selection and processing techniques.

Service Contents

Material performance optimization suggestions (such as balance schemes for wear resistance and conductivity)

Processing technology guidance (key parameters including melting temperature control at 1100°C - 1200°C, pulling casting speed at 10 - 30 mm/min, etc.)

Welding technology consultation (various methods such as argon arc welding and laser welding can be selected)

Quality control and certification

Certification System

ISO 9001 Quality Management System Certification

CNAS Accredited Testing Capabilities (chemical composition analysis, mechanical performance testing, etc.)

Compliant with multiple national standards such as GB, JIS, ASTM, etc.

Process Control

Full-process spectral analysis, eddy current testing and other detection methods

Strict control of chemical composition (for example, the Sn content in QSn4-0.3 is 3.5%-4.5%, and the P content is 0.20%-0.40%)

Delivery and supply chain advantages

In stock supply

Standard specifications of phosphor bronze products are in ample stock (such as C5191, C5210 etc.)‌

Some suppliers offer a fast response service with delivery within 1 day‌

Production cycle

Delivery cycle for regular products: 3 - 20 days

The rapid production plan (such as optimization of the horizontal casting process) can shorten the production cycle

Supply Chain Management

Our own smelting production line enables full-process control.

Raw materials are strictly selected (to control the purity of electrolytic copper) to ensure stable quality.

After-sales service system

Service Commitment

Respond to customer requests within 24 hours

Free repair or replacement of faulty products within the warranty period

Technical Support

Long-term technical consultation and process optimization services

Regular follow-up visits to collect usage feedback

Problem resolution

A professional team analyzes the causes of the quality issues (such as pores, non-compliance with density standards, etc.)

Proposes process improvement solutions (optimizing melting and casting parameters, etc.)
