Import Brass Weight — Buy in Bulk from Supplier in Thailand

Brass Weight from Thai-nichi Corporation is a precision mass standard manufactured from brass, a copper-zinc alloy selected for its stability, corrosion resistance, and non-magnetic properties essential for accurate gravimetric measurement. The weights are produced with a polished finish that protects against surface oxidation and ensures consistent handling characteristics. Thai-nichi Corporation, based in Bangkok's Minburi district, distributes these weights for laboratory calibration, educational demonstration, and industrial quality control applications where traceable mass standards are required. The exact alloy specification, nominal mass values, and tolerance class are not stated in the source and must be confirmed directly with the supplier.

Brass as a weight material offers distinct advantages over steel alternatives: its non-magnetic nature eliminates magnetic susceptibility errors in precision balances, and its resistance to atmospheric corrosion reduces mass drift over time compared to unprotected carbon steel. Standard brass weights for laboratory use are typically manufactured from free-machining brass with controlled lead content for dimensional stability, though lead-free alternatives exist for environmental compliance. The polished finish described by Thai-nichi serves both aesthetic and functional purposes, reducing surface area for contaminant adhesion and providing a smooth surface for careful handling with forceps. Typical brass density is approximately 8.47 g/cm³, slightly lower than steel at 7.85 g/cm³, meaning brass weights of equivalent mass have slightly larger physical dimensions.

The primary buyers for these brass weights include metrology laboratories requiring working standards, universities teaching analytical chemistry and physics, pharmaceutical manufacturers with in-house calibration programmes, and food processors needing check weights for production scales. Industrial quality control departments use brass weights for routine balance verification under less stringent conditions than reference standards. Buyers should confirm with Thai-nichi whether their weights conform to specific national or international standards such as OIML R111 (weights of classes E1 to M3), ASTM E617, or JJG 99-2006 (Chinese national standard). The supplier mentions compliance with ISO standards but does not specify which standard or certification body. Packaging, minimum order quantities, and precise lead times are not detailed and require direct enquiry.

Thai-nichi Corporation is located at 69/113 Perfect Place 20/4, Ramhamheang 164, Minburi, Bangkok 10510, Thailand. The supplier holds an imported supplier tier and harbour trust tier designation, indicating they are a registered entity on the platform with some verification. The Minburi district location places them within Bangkok's eastern industrial and residential zone, with reasonable access to Suvarnabhumi Airport and Laem Chabang Port for international logistics. The response rate is recorded at 0.00% with zero average response hours, which may reflect data collection timing rather than operational status, but buyers should test responsiveness before committing to orders.

The company positions itself as a supplier of precision and reliability products for industrial, laboratory and educational markets. No information is provided about years in operation, number of employees, annual turnover, manufacturing capability versus trading function, or specific client references. The source description mentions ISO standards compliance and flexible minimum order quantities, but does not identify which ISO standards, certification numbers, or actual minimum order thresholds. Buyers should request current ISO 9001 or ISO/IEC 17025 accreditation certificates if quality management or calibration laboratory competence is claimed, and verify the scope of any certification to ensure it covers brass weight manufacturing or distribution.
