8. Professional FAQ: Technical Terms Explained

Q1: What is “High-Silicon Hypereutectic Aluminum Alloy” and why is it used?
A: This alloy contains a silicon content higher than the eutectic point (typically 12–20%), providing superior hardness, low CTE (coefficient of thermal expansion), and excellent scuff resistance—ideal for automotive pistons enduring high thermal loads.
Q2: What does “CNC Finish Machined” indicate for piston production?
A: Computer Numerical Control (CNC) machining ensures micron-level dimensional consistency, optimal surface finish, and enables production of complex geometries with roundness <±0.005mm tolerance, meeting ANSI B46.1 specifications.
Q3: How does “Graphite Coated Skirt” benefit piston operation?
A: The dry-film graphite coating reduces friction between the piston skirt and cylinder wall, minimizing wear, preventing cold start scuffing, and enhancing overall efficiency for high-cycle operations.
Q4: What is “Compression Height” and why is it important?
A: Compression height (34.1mm for this piston) is the distance from piston center pin to top surface. It affects combustion chamber volume and compression ratio, thus impacting engine power and efficiency.
Q5: What industry standards certify quality and safety of this piston?
A: The Piston 93736247 Chevrolet LDE LCU 73.8MM 1.6L is manufactured in facilities holding ISO/TS 16949 and ISO 9001:2015, fully aligning with global automotive and industrial norms.
Q6: What is the typical warranty and replacement policy?
A: Standard warranty covers 24 months / 80,000 km (whichever comes first), with defect traceability and priority replacement protocol according to ISO 9001 QMS document control policy.
Q7: How are pistons shipped and what is the lead time?
A: Pistons are packed with multi-layer anti-corrosion VCI materials. For standard orders, delivery is 18-25 working days; for custom batches, 22-34 working days post approval.
