Product Description

ТБ2013/TM-2/108SP Bimetallic Strip

Product Overview

Standard Designations & Core Composition

• Product Grade: ТБ2013/TM-2/108SP
• Composite Structure: Typically consists of a “high-expansion layer”  and a “low-expansion layer” ; interfacial bonding strength ≥140 MPa
• Compliant Standards: Adheres to GOST 28561-90 (Russian standard for bimetallic strips) and IEC 60694 for thermal control components; compatible with EU RoHS requirements
• Manufacturer: Tankii Alloy Material, certified to ISO 9001 and ISO 14001, with in-house alloy formulation and composite bonding capabilities to match the grade’s specific performance requirements

Key Advantages (vs. Generic Bimetallic Strips)

1. Broad Temperature Adaptability: Operates stably in -50℃ to 250℃ (continuous use), with short-term resistance up to 300℃—surpassing standard bimetallic strips (limited to ≤200℃) and suitable for high-temperature industrial scenarios (e.g., engine compartment sensors).
2. Low Thermal Hysteresis: Hysteresis error ≤3℃ (between heating and cooling actuation points) at 150℃—critical for precision temperature control (e.g., industrial oven thermostats) where repeated on/off cycles require consistent thresholds.
3. Strong Fatigue Resistance: Withstands ≥15,000 thermal cycles (-50℃ to 250℃) without interfacial delamination or performance decay—3× longer service life than low-grade strips, reducing maintenance costs for long-service equipment (e.g., HVAC systems).
4. Vibration & Corrosion Resistance: Transverse tensile strength ≥460 MPa ensures structural stability under vibration (compatible with IEC 60068-2-6 vibration tests); optional zinc-plating provides 96-hour salt spray resistance (ASTM B117) for humid or corrosive environments (e.g., marine equipment).
5. Consistent Dimensional Precision: Available in common thicknesses (0.15mm–0.8mm) and widths (10mm–200mm) with tolerance ≤±0.005mm (thickness) and ≤±0.1mm (width)—enabling automated stamping and integration into standard industrial components.

Typical Applications

• Industrial Temperature Control: Thermostats for industrial ovens, boilers, and HVAC systems; temperature regulators for plastic molding machines (operating at 120℃–200℃).
• Overheat Protection: Thermal circuit breakers for electric motors (e.g., industrial pumps, compressors) and power transformers—prevents burnout by disconnecting circuits at 150℃–250℃.
• Automotive & Marine: Temperature sensors and protectors for engine compartments (automotive) and marine equipment (resistant to vibration and saltwater corrosion).
• Precision Instruments: Temperature-compensating elements for pressure gauges, flow meters, and MEMS sensors—offsets thermal expansion errors to maintain measurement accuracy.
• Household & Commercial Appliances: Overheat protectors for electric water heaters, air conditioners, and commercial refrigerators (stable performance in high-humidity environments).
