Introduction

National Standard of the People's Republic of China GB/T 26063—2023 Interpretation of Beryllium Aluminum Alloy Standard

1. Background and Significance of Standard Formulation

GB/T 26063 series standards have been an important basis for the production and application of beryllium aluminum alloys since their release in 2010. This revision is based on industry technological progress and market demand, and has comprehensively updated the original standards, focusing on improving product quality requirements and technical indicators.

Comparison of major revisions

Old version requirements (2010)	New version requirements (2023)	Explanation of changes
The content of Ag, Co, and Ge elements is not specified	The content requirements of Ag, Co, and Ge elements have been added	The detection requirements of impurity elements have been added to improve the level of material purity control
The tensile strength of BeAl-F grade is ≥250MPa	The tensile strength of BeAl-F is increased to ≥270MPa	The requirements for mechanical properties of materials have been improved
Physical parameters such as elastic modulus are not specified	New indicators such as elastic modulus and Poisson's ratio	Improve the evaluation system of material physical properties

2. In-depth analysis of technical requirements

Chemical composition requirements

Take BeAl-F and BeAl-Z as examples:

BeAl-F: Beryllium content is 60.00~65.00%, aluminum is the balance, and impurity elements such as Fe and Si are strictly controlled at a low level.
BeAl-Z: Beryllium content is increased to 60.00~69.00%, and quantitative requirements for Ag, Co, and Ge elements are added to further optimize alloy performance.

Mechanical properties upgrade

It can be seen from Table 3:

Grade	Tensile strength Rm MPa	Specified plastic elongation strength Rpo.2 MPa	Elongation after fracture A25mm %
BeAl-F	≥270	≥170	>2.0
BeAl-Z	≥190	≥165	≥1.5

3. Implementation suggestions and precautions

Production link

Strictly control the procurement of raw materials to ensure the purity of beryllium, aluminum and other added elements.
Optimize casting and powder metallurgy process parameters, focusing on temperature control and mold design.
Equipped with advanced testing equipment, such as tensile testing machine, thermal conductivity tester, etc., to ensure that various performance indicators meet the standards.

Quality control

Suggestions for enterprises:

Establish a complete quality traceability system to record the production and testing data of each batch of materials.
Strengthen internal employee training to enhance the understanding and implementation of new standards.
Regularly communicate with industry experts to keep abreast of the latest technology and standards.
