Steel Wire (100gm)
Product Code : SCL-PLE-11758
The StemAids Steel Wire (100g Spool) is a high-carbon industrial-grade metallurgical standard engineered for the empirical study of material strength, elasticity, and resonance. Optimized for Secondary and University-level physics, this wire is the primary medium for Searle’s Apparatus experiments and Sonometer investigations. Manufactured to ISO 9001:2015 standards, it provides a high-modulus, durable solution for quantifying the physical limits of ferrous alloys within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Elasticity Quantification: Enables the physical study of Hooke's Law, allowing learners to apply tensile stress to determine the Young’s Modulus of steel, demonstrating its superior stiffness compared to brass or copper.
- Acoustic Resonance Analysis: Serves as the high-tension string for Sonometer experiments; supports the analysis of how the frequency of a vibrating string relates to its tension and linear mass density.
- Thermal Property Evaluation: Facilitates the study of the coefficient of linear expansion when subjected to controlled heating in a steam jacket or electrical current.
- Durability Assessment: Allows students to evaluate the "yield point" and "breaking stress" of ferrous materials compared to non-ferrous alloys in structural engineering modules.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring moisture-absorbing silica packets and vacuum-sealed wrapping to prevent "red rust" or pitting during maritime transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and Material Data Sheet (MDS) outlining tensile strength specs.
- Shelf Stability: Hardened surface finish ensures the wire maintains its specified diameter and elastic properties even after long-duration storage in high-humidity climates.
Direct OEM Sourcing Advantages
Procuring StemAids Steel Wire directly ensures vertical manufacturing control:
- In-House Gauge Verification: Every spool is batch-tested for diameter uniformity using laser micrometers, ensuring that "cross-sectional area" (A) remains constant for precise Stress/Strain calculations.
- Batch-Tested for Uniform Reliability: Samples from each production run undergo load-cycling to ensure the elastic limit meets international educational standards.
- Direct Factory Customization: Ability to procure specific gauges (SWG) or specialized "Piano Wire" grades for advanced acoustic research.
- Manufacturing Control: Direct oversight of the drawing process ensures a smooth finish, reducing the risk of "stress concentrators" that cause premature wire failure during student experiments.
