Chapter 1 Basic Knowledge of Tungsten Alloy Weights
Tungsten alloy weights play an important role in many fields. Their unique physical and chemical properties make them highly favored in industrial, scientific research, and commercial applications.
1.1 Definition and Classification of Tungsten Alloy Weights
Tungsten alloy weights are standard mass instruments made primarily of tungsten and combined with other metal elements (such as nickel, iron, and copper). They are used to calibrate balances and scales, ensuring the accuracy and reliability of measurement results. Their high density, corrosion resistance, and mechanical strength give them significant advantages in precision measurement. Tungsten alloy weights are available in various categories based on their application, accuracy level, and shape, meeting diverse measurement needs.
1.1.1 Definition of Tungsten Alloy Weights
tungsten alloy weights can be understood from three perspectives: composition, function, and application. First, from the perspective of material composition, tungsten alloy weights are alloy products primarily composed of tungsten, typically containing over 90% tungsten, supplemented by elements such as nickel, iron, or copper to enhance their processability and mechanical strength. Tungsten’s high density (approximately 19.25 g/cm³) allows it to achieve a high mass within a small volume, a key characteristic that distinguishes it from other metal weights, such as stainless steel or brass. The chemical stability of tungsten alloys also makes it resistant to oxidation and corrosion over long-term use, ensuring consistent quality.
From a functional perspective, tungsten alloy weights are standardized instruments used to calibrate and verify the quality of weighing instruments. In metrology, the quality of weights must conform to international or national standards (such as OIML or JJG standards) to ensure their reliability during the calibration process. Tungsten alloy weights, due to their high density and low volume, are particularly suitable for calibrating small balances requiring high precision, such as laboratory analytical balances or microbalances. Furthermore, tungsten alloy weights exhibit excellent wear resistance, maintaining their surface finish and mass stability even during frequent use, thereby reducing errors caused by wear.
From an application perspective, tungsten alloy weights are widely used in laboratories, industrial production, and commercial metrology. For example, in the pharmaceutical industry, tungsten alloy weights are used to calibrate high-precision scales to ensure the accuracy of drug formulations; in the jewelry industry, their high-precision properties meet the needs of precious metal weighing; and in scientific research, tungsten alloy weights provide a reliable mass benchmark for high-precision experiments. The terminology definition of tungsten alloy weights extends beyond their physical properties to encompass their functional role within standardized metrology systems, making them an indispensable component of modern metrology.
