Overview
UNS R60705 Zirconium Alloy Plate (Zr705) is not treated as a general corrosion sheet.
It is normally used as a starting material for manufactured parts, especially when the end component is defined by:
- engineering drawing
- BOM / material list
- replacement part requirement
- machining process requirement
In many real cases, buyers are not purchasing "plate stock", but a pre-material for shaped zirconium alloy components.
This is the key difference from commercially pure zirconium plate.
Typical Supply Logic
Zr705 plate is usually selected in these situations:
* the part is defined as zirconium alloy in engineering documentation
* final geometry is not a flat sheet, but a machined component
* thickness is only a starting condition, not final geometry
* cutting + machining is expected after delivery
Before quotation, the critical point is not only size - but whether Zr705 is mandatory in your specification chain.
Specification Overview

| Product Name | UNS R60705 Zirconium Alloy Plate |
| Common Name | Zr705 Plate |
| Material Type | Zirconium alloy (niobium-stabilized grade) |
| Form | Plate / machining blank |
| Supply Condition | Hot rolled / annealed (depends on size route) |
| Thickness | Based on drawing or stock requirement |
| Width & Length | Standard sheet or cut-to-drawing |
| Edge Condition | Saw cut / milled edge / profile cut |
| Surface | Pickled / machined / as-rolled |
| Processing | Cutting, CNC machining preparation, drilling support |
| Documentation | Basic material traceability on request (no fixed certification claim) |
Before Quotation
Please confirm below information clearly before we check supply route:
- Required grade: Zr705 / UNS R60705 or equivalent specification
- Source of requirement: drawing / BOM / project specification
- Starting thickness (important for machining allowance)
- Final component shape (rectangular or profiled)
- Quantity (pcs / kg / sheet count)
- Surface requirement (if functional surface is involved)
- Machining scope (cut only / drilled / fully machined)
- Tolerance requirement (if applicable on finished part)
If this is a replacement part, previous supplier data or sample photos are more useful than a general description.
Engineering Use Logic
This plate is often not used directly. It becomes:
* blocks after cutting
* flange blanks after machining
* support plates after drilling
* structural zirconium alloy parts after finishing
So the material choice is linked to final geometry, not appearance.
Zr705 is usually used when documentation requires:
* UNS code consistency
* alloy grade control
* structural reliability in fabricated parts
It should not be automatically replaced by pure zirconium grades without confirmation.
Unlike standard sheet supply, thickness here is often:
* machining allowance
* pre-processing stock condition
* structural starting dimension
Final thickness is usually defined later by machining.
Processing Route
Typical flow for Zr705 plate supply:
* ingot / slab preparation
* rolling into plate form
* annealing if required
* surface conditioning (pickling / machining)
* cutting into sheet or blank size
* edge finishing (straight / profile)
* packing for machining or fabrication use
Each step may vary depending on thickness and order size.

Application Scenarios
Machined Structural Blanks
Used as starting plate stock for zirconium alloy parts that require milling, drilling or final shaping after cutting.
Replacement Plate Parts
Used when existing Zr705 components need to be reproduced according to old drawings, samples or material records.
Support Plate Components
Used for support plates, spacer plates, clamp plates or fixed parts where alloy grade and thickness matter.
Profile-Cut Components
Used for non-rectangular zirconium alloy plate parts that require profile cutting, holes, slots or edge preparation.
Bolted Assembly Parts
Used for zirconium alloy plates with bolt holes, mounting positions or assembly surfaces that need layout checking.
Heavy Machining Stock
Used as thicker plate stock when final dimensions require machining allowance before reaching the finished part size.
Packing Considerations
* Flat plates separated by protective sheet
* Machined blanks protected from edge damage
* Heavy plates packed in wooden case or pallet
* Surface-sensitive material separated to avoid scratches
* Profile-cut parts packed individually if required
Packing method depends heavily on final geometry and surface condition, not only weight.
FAQ
Q1: Is Zr705 the same as Zr702?
A: No. Zr705 is an alloy grade, Zr702 is commercially pure zirconium. They are not interchangeable unless specified.
Q2: Can Zr705 plate be used directly?
A: In most cases it is used after machining or cutting, not as final flat product.
Q3: What is the most important information for quotation?
A: Grade source + drawing + thickness allowance + final geometry.
Q4: Can you supply shaped plate instead of rectangle?
A: Yes, if drawing is provided. Profile cutting can be reviewed.
Q5: Is surface finish important?
A: Only when it becomes a functional surface or assembly surface.
Q6: Can it replace previous supplier material?
A: Yes, but previous specification or sample data is required for confirmation.
